Making Cast Iron Bronze - Ingot Give Away
ฝัง
- เผยแพร่เมื่อ 30 ก.ย. 2024
- I am making cast iron bronze again with a slightly different method, some crude tests and an ingot give away.
Following on from last weeks video I make cast iron bronze again using cast iron, copper and aluminium but with a slightly different method.
This week I show how I make this cast iron alloy, a aluminium bronze with cast iron and cast it into some 1kg ingots. As I recently reached 1000 subscribers I have 3 of these polished bronze ingots to give away.
The give away video will be later this week.
This is an extremely hard bronze and is well suited to swords, axes, knives, hammers and other similar tools. It should also hold an edge well.
This cast iron bronze has a beautiful golden bronze colour.
The recipe for this weeks cast iron bronze alloy is:
70% Copper
20% Cast Iron
10% Aluminium
Expect losses of 30% to dross as it currently stands.
To make this bronze, melt the copper and the cast iron together, add the aluminium when the copper has melted and mix well, keep heating until everything's melted, skim and pour. Temperatures need to be kept in the 1150C - 1300C range and must be mixed extremely well.
This cast iron copper alloy recipe was provided by Daniele Bosco. You can see his TH-cam Channel here / channel
Daniele is from Italy and has studied metallurgy for 5 years.
He has several other recipes for this cast iron bronze which I hope to try out in the future.
Hope you all like this video, happy casting.

Tried this one again, still a few issues, but got some lovely ingots to give away. Might not be easy to cast with, but if you like your ingots and don't mind losing a bit to dross this is a great metal. Cheers all, hope you enjoy the video. Best wishes Andy 🥂🥂🥂
MeltandCast Strange I thought the flashes I saw in the last video were small” thermite reactions from iron oxide mixing with the molten aluminum. I didn’t think about trace magnesium causing that reaction.
Have you tried acid etching a slice to examine under magnification?
That takes a beautiful polish...how long does it stay like that?...
Due to the narrow temperature range of pouring, perhaps centrifugal casting is the ticket to successful end results on a project. What do you think?
@@stanervin6108 No mate not tried that... not sure if I will... I'll probably try this recipe a couple more times and then move on to other things... Cheers Andy 🍺🍺🍺
I think this was marvelous experiment.....so mixture is 70% copper....20%cast iron....10% aluminum...and 2.5% tip of stir rod?.😁....it was a great melt.
Haha, that chemical reaction definitely took place and made some hellish heat for sure.
Perhaps send it to Cody's lab hes a geologist could do some neat stuff with it
I second this - he'd have some great fun with it, from analyzing it with his spectrometer to probably making a nosecone for a mars probe. ;)
I can’t wait to retire so I can do cool stuff like this
you would need a metallurgist, or need to send stones ;P
@@Alrion1704 Cody is sort of a "mad genius of all trades". He mines, grows plants, does experiments on precious metal recovery / carbon capture / charcoal generation, recovers range lead, etc etc etc. He's currently in the middle of nowhere in NV building 'chicken hole base' which is meant to emulate a mars mission.
my metallurgy training and study's can back to me with power when i saw your first vid on this
aluminum always has a thin oxide layer on it and iron oxide and aluminum oxide make thermite, and with the magnesium impurity you where making thermite in your melt.
but the copper is mixing and interfering with the aluminum and iron with atmospheric o2 thermite reaction.
your still losing a lot of aluminum as a gas in your melt, but the same happens when you make brass with the zink
so id say this is more in the famaly of brass for the melt but bronze for finished product
but it is at the end mostly copper with iron or as you say "Cast Iron Bronze"
id love to see a cut and acid etching of one of the ingots as well as how it melts a second time as brass will out-gas zink with each melt and some other alloys will make non alloyed pockets in the castings with each melt
also my metallurgy science demands to know its physical property's like pull tear and compress strength, its corrosion resistance, its hardness (it make a great bell) is ductility or brittleness, is it still ferrous? (will a magnet stick to it?) whats its electrical property's? whats its magnetic flux property's? i have so meany questions.
Can you forget it? You should send one to demolition ranch, Alex steel, bigstackD, all pretty good you tubers and see how they hold up to a few test.
I was just thinking that. If Alec Steele learns of it, he might just make some himself and then we'll see a 100 part series of him trying to make a sword or something of that nature. I'd like to see that.
Or How to Make Everything.
"Today we're going to invent an alternative bronze, called Iron Bronze, or Daniel's Metal. Now, since we haven't invented Recipes or Printing yet, I'll be eyeballing this"
I'd love to see Alec Steele try his hand on this, alternative is to grind up into smaller chunks and re-melt it, and try re-casting it, or both!
Send one to clickspring as well. Maybe he’ll find a use for it
I guarantee this will
Shatter into a thousand pieces if hit by a bullet
Would love to see a snap test to check grain properties. Would be interesting if it created small hard crystals like cast Iron or Bronze, or if the copper gives it a little flexibility.
And a proper HRC test
Interesting that your "skinny bar" had much tighter grain structure and a smoother overall finish. That was the bar that you had to reheat to be able to pour it. I can't help but wonder if you need to heat for a longer period of time to let it do it's magic........
Quite possibly... I also noticed that... definitely worth a try... Cheers Andy 🤔🤔🤔
Or you can melt, let it cool to cherry red and then reheat and melt again for pouring.
Maybe do so a total of two or three times and see what happens.
Scary part there is he got dross with both melts. If that much dross forms each reheat, he could be looking at 50% or more material loss.
@@angelaabrams9108 The dross that came out on the remelt could be the result of oxidation caused by an oxygen rich atmosphere. As a test, I wonder what would happen if on the remelts, the crucible were flooded with argon to block oxygen out of the mix. Doing that would require using an induction furnace for heating tho..... But then we'd be getting into exotic metallurgy....not the realm of a hobbyist ....LOL!
I wonder if this recipe needs to have glass covering it at the top like Wootz steel is made. The glass melts first, and covers the metal so that oxygen can't interact with the metal while it's bonding. Might be worth a test or 3...
I think the trick to making this alloy may be to leave it in the heat for longer with occasional stirring and a higher heat if possible. Why I say this is because it seemed to be a little bit clumpy on the first pour which I think is a sign of a non-homogeneous melt. But I'm just a guy that watches too many videos like this and the only school I have similar to this is my immersion in chemistry of which I haven't completed yet :/.
The last ingot did look a lot better than the others didn't it ? 🤔🤔🤔
I would be most interested in the electrical properties of this of this alloy. In RF and electrical systems we use Beryllium Copper extensively. A new lower cost alloy would be a great thing. If the resistance is low enough it could improve the safety of structural wire. The applications are nearly limitless, if it has good electrical properties.
I had a thought that if the alloy maintains some of the magnetic properties of the iron you may have something very special for building coreless transformers. Improving the efficiency of transformers has nearly limitless applications and benefits. Everything from power grid sized transformers to microelectronics would benefit.
iron has a higher resistance than copper by a factor of ~5.
Since the losses are almost entirely Fe and Al, and those are by far the cheapest and most abundant of the three metals in the melt, this seems worth the loss to me!
I don't think I've ever had my forge up past 2400, kind of scared to go that high...but that is a gorgeous bronze. Some day! Great video
My fiance and I are going to be keeping an eye on your progress and, hopefully, trying out this alloy in our smithy. Looks FANTASTIC!
And hello from Ohio, US!! :D
Thanks Eden, and greetings from not so sunny Cambridge !!! It's not so easy to make, but it's worth a go. Lots of people would like to know how it might forge. Daniele says it can be hot forged. Do let me know how you get on, I'd be really interested to see the results. Cheers Andy 🍺🍺🍺
This gets more interesting with each pour, I'm impressed with the hardness/ductility test. Subscribed to see where this goes.
I keep thinking about the sword of Goujian with that gorgeous golden colour and hold out hopes you and Daniele have discovered something genuinely new and useful.
I really hope you figure out how to homogenise the pot and limit the oxidation going on. I wonder if any other traditional bronze ingredients will alter the alloy predictably. like a pinch of tin to increase hardness or lead for softness. I haven't a clue what bronze uses a flux, but it looks like the lumpy pour could do with some? Would adding carbon somehow give a steel bronze, instead of iron bronze? Keep me well away from boiling metal and dry ice, lol.
If I had a setup like yours, I'd be ordering all sorts of elements online and chucking it in to see how it affects the stew. One would think all this has been figured out by now, but the comment section has me wondering.........
I’d love to see this go to a blacksmith to see if he could make a knife.
Knifes are a good test of a materials properties.
I certainly would like to try it out, that's for sure!
Liam Armstrong i had the same thought as i was watching this video. It would make a handsome yellow knife too.
Yes, a forge test would be great! How does this alloy take a heat, Does it forge weld? Does it deform without cracking? Can it be tempered? Do send a piece to a blacksmith to do these tests.
@@tree_relics I'd gladly do some tests with it! I only just today got my gas forge set up, so now I have access to both coal and gas. Given that it is a copper-based alloy, I would make a guess that it does not really forgeweld as steel does, and that it might be red-short, but it should work-harden, but I haven't an idea what aluminium and iron+the bit of carbon does in what is essentially a bronze, we touched metallurgy only very briefly in blacksmith school. :)
Very good idea. Im wondering how bendable, how well it takes/keeps and edge,... The works!!
Now give to a blacksmith to see how it is when worked.
I would love to see you make up an ingot and do a collaboration with a blacksmith TH-camr to see how well they can forge it out and how well it can hold up to abuse
Alec steele
I second Alec Steele. great guy with an amazing blacksmith channel.
Agreed on sending a sample to Alec Steel
Now that is beautiful - love the crystalline structure on the outside, but when you cut it - wow - it looks mint! Well done!
20:47 actually that was testing strength and ductility. The point of failure would've indicated its strength while the mode of failure (shattering vs deforming) would've indicated ductility. Hardness requires special tools or sets of standard files.
This could make an absolutely beautiful damascus!
I hope we see more of this new alloy and are able to find a suitable recipe for casting in molds!
It'd be interesting to see what the hardness is
Ave did a video where he tested rockwell hardness by bouncing a ball bearing down a straw and seeing far it bounced as a cheap way of doing it
Even cheaper is to just buy the hardness testing files... I'd start there.
@@Mmouse_ OK, so why don't you buy them and mail them.
I'd like to see what Clickspring could do with a chunk of that alloy
If it's really as hard as steel, he'd be stuck with his files I think. His lathe and cnc machine are pretty small, and he always seems to work with softer metals. I love his stuff, but he might not be the right choice
@@gamemeister27 Maybe, maybe not. Hard materials usually take a fine polish although they are more difficult to work as you point out. If there is anything exceptionally shiny, it's Clickspring's work
Clickspring's work is amazing, I saw his card press video a while back.... stunning work. Thanks for the reminder popped him a sub !! Andy 👍👍👍
Well, I must admit my surprise that they stood up to the test so well. How magnetic is the slag? Could most of the iron be getting rejected into slag? That would leave you with essentially aluminium bronze which would behave like your test piece. Great video again. Thanks for making it. Mike
Good point Mike, I didn't think to test that, I'll do that next time I'm in the shed. I'll report back on the next video. I'm also starting to think i'm just making aluminium bronze albeit in a much more convoluted way... Commercially produced aluminium bronze does have iron in it, whereas most TH-cam aluminium bronze is just copper and aluminium... Of course it could be I'm just extremely bad at making alloys... Daniele's managed to make this with few losses - and been able to sand cast it too... Cheers Andy 🍺🍺🍺
@@MeltandCast The alloy you are making is likely just C954 aluminum bronze, that much iron simply isn't going to dissolve in copper. It will separate out as a copper containing iron alloy. That will also mop up all the carbon that was in the original cast iron (which is insoluble in a copper alloy), which will probably form a bunch of cementite, which would explain the thick, slushy crud in your crucible.
That's pretty much what Luckygen and F st said, that the carbon and resulting graphite were incompatible... I'll make this one more time as Daniele has a suggestion, but I think the result will be similar. I have a lot of other projects I want to work on, so I won't be pursuing this too much afterwards, apart from perhaps making some ingots to send to other channels to run some tests. Forging, stress, shear, strength tests etc. From the comments a lot of people would like to see some numbers, so I'll try and make that happen. Cheers Andy 🍺🍺🍺
that is gorgeous! I would love to know later on how well it resists oxidation.
Interesting video again! Wow I thought I had mistaken myself, but I saw it right! congrats with passing 1k subs, already heading to 2k! How did you do that? You scared me a bit by stepping over that red hot full crucible just before the first melt. Nice ingots :)
Be interesting to do a nital etch on this and put it under a good DIC microscope
I would not mind if it got a full metallurgy test of mechanical and corrosion resistance properties. That most likely would be cost prohibitive.
@@ScooterFXRS corrosion resistance is cheap and easy - put it in some acid,or salt water. Compare to other metal under the same test conditons
Abrasion resistance is another matter entirely.
@@IPostSwords lol excellent, We will expect a full analysis in the morning.
Soft enough for vise Jaws to mark it up.
Vice jaws will mark high carbon steel. Marks dont mean a metal is soft.
Perhaps it can be heat treated.
@@barongerhardt My pondering was just an abbreviated form of me wondering if this alloy can be hardened and tempered by heat treatment.
IOW, is this a heat treatable alloy?
If so, it would open a lot of possibilities for it.
@@barongerhardt That's what I was thinking, since it's a copper alloy. But, I've been wrong before.
@@fortj3 since it has some cast iron in it (cast iron contains carbon), it could maybe be quenchable?
There's a new way to make batches of these metals now that involves an arc welder of vacuum chamber and inert gas and the molds are super cooled copper molds.
Almost seems like an aluminum bronze, but harder...
How much iron are you losing in the dross? Any iron not dissolving in the copper would tend to float.
I'll run a magnet over it next time I'm down in the shed. I didn't think to try that, I just used a magnet on the ingot itself.... good call... Cheers Andy 🍺🍺🍺
I noticed how lumpy the pour was. I wondered the same thing. How can you keep everything blended and liquid when pouring? Great experiment! I love the color
Maybe sand casting an ingot would help help?
Really fascinated by this compound! I am a blacksmith and am wondering if this could now be hammer forged into items or if it should only be cast into shape... What do you think??? Looking forward to the giveaway! I'd love to experiment with it in my shop!
I have a blacksmith friend, if I do make this again I'll give him a piece to forge. I'm fairly sure Daniele said this can be hot forged, not 100% sure, but I think so... Cheers Andy 🍺🍺🍺
Really interesting thx to showing, looks amazing how you do it.
Awesome job man !!!!! Unique for sure !!!! Love it !!!! Dang that is strong!
Thanks David, enjoy the weekend buddy... Andy 🥂🥂🥂
Subscribed, glad TH-cam recommended this as I love these types of videos. Great pour and interesting look into alloys. Looking forward to future videos
Thanks for the sub Edward, glad you enjoyed it mate. Cheers Andy 😎😎😎
Please repour the first attempt ingot
Excellent job, every pour is a learning experience. Enjoyed the video, keep up the great work.
Thanks James 😎😎😎
Sir IT LOOKS AS IF YOU HAVE A REAL WINNER!!! From the tiny bit I have seen that metal has many uses!!!!!
If it works you may have the new gold !!!!
Many jewelry items could be made from it if it wares properly. And if it is workable. The substitutes for gold now are pitiful!!!!
Do another video and heat a piece and work it to make a nail. That’s simple but it will show the workability.
Oh men’s jewelry could come back!!!
You can pick up some fairly cheap hardness testing files online - it'd be interesting to see how hard this is - also does it hold an edge etc.
If you reach out to AvE/Applied Science/Cody/this old Tony/Project farm I'd imagine they'd be interested - if you could get Ben from applied science involved and he's up for it, he'd do some really rigours testing on this - he can analyse it and has an electron microscope.
Lovely looking result and thanks for showing that experimentation can be hard work. Hope you've inspired enough people to contribute refining the process and show some finished works.
Thanks Tim, glad you enjoyed it mate 🥂🥂🥂
its awesome to see you adopt new ideas like testing them after or working on them more
looks like the oxide layers forming very quickly during pouring you could try adding some borax before you add the al, and before you poor maybe a tea spoon for the amount your pouring.. would also help you drop your losses down to maybe 1/4 as your excluding some oxides in the initial mixing. but i'd love to see how these temper and harden looks interesting. i'd love to throw some tin in there too just for the crystals sake
Hmmm..add a pinch of titanium?
I commented in the previous video that this reminds me of the mythical Elysian Bronze used by the god Hephaestus/Vulcan to make the weapons and armor of the Olympian gods.
I wonder what it would forge like. Or if it could be hardened, I suspect with its high copper content it could be work hardened. I wonder if you could collaborate with Alec Steele to forge something with it. 🤔
I checked for an alloy similar to yours and could find anything like it for sale. So, yes, everything I see says it's either brand new or lost in ancient times.
Might make nice sword fittings. Although besides a Bronze style sword I don't think it's going to out perform good steel.
I wish I saw this video like, a month in the future. Because now I have to wait to see people like Alec Steele pick this up and do stuff with it...
I really like the one with the two beads, it has a certain charm to it. Love the cast iron bronze idea
hmm.. with copper as the main component this metal is probably prone to work hardening so the more you hit it the more brittle it should become..
Amazing experiment. I'll be excited to see what kind of quality it lends to a tool or blade.
Fascinating. Will you be testing the tensile strength any time soon? I am more than interested to see how it compares to iron and steel. Thanks.
If you don't mind I'd actually like the cut piece xD. It shows the inside of the metal.
Give the bigger ones to Alec Steele, he can probably make some kind of a sword with it.
Give the little one of those 3 to Shurap, since he does a lot of little knifes out of pattern layered metal.
The three larger ingots will be given away soon, the small one I'll be keeping... Hit the bell so as not to miss the give away... Cheers Andy 🍺🍺🍺
it has a nice golden colour , if its a good strength it could be used to make a good Excalibur like sword
I would love to have an ingot of this. Not sure what I would decide to do with it, since I have a lot of ideas for ways to use it.
Very interested in copying an doing an axe as well as seeing how alloy works in heat transfer via being a skillet.
That stuff is super cool. It would make for interesting medium to make stuff from
I wonder how it would do if you used borax or glass as a flux to keep the surface from reacting.
What about the two little buttons that came off of the bar you cut? I'd take one of those off your hands for ya!
Just wondered what sort of result you would get if you added say 5% zinc to the mix?
Man, I would love to get my hands on your original large ingot. I could try machining or forging it or just making some artwork out of it. I love the look of the imperfectly mixed cast iron and copper/aluminum. Bet it would look amazing machined flat and polished up.
Incredible material and great vids man. Just recently found your channel and will be sticking around. Id love to work with some of these materials, keep up the good work! Subscribed!
Thanks for the sub Canon... Keep an eye out for the give away video.... you never know hehe. Enjoy the weekend mate... Andy 🥂🥂🥂
I'd say you need a flux, and a bit more heat to get it all to properly dissolve and incorporate into a genuine alloy, as well as pourable fluidity
I'll try a flux or cover flux next time... Cheers Andy 👍👍👍
Seconding the flux. My guess is that a lot of the loss is just oxide. Silica, ground up hardwood charcoal, or borax might be good things to try among other things. It's hard to know though what will be best. Maybe knowing the exact composition of the dross would help guide the optimal choice.
@@gamerdude873 Also I think that aluminum is actually reacting with the iron oxide that is forming when the cast iron gets that hot - it's like a mini-thermite formation. Part of the reason for that loss.
@@gamerdude873 I'd be inclined to try borax and tartaric acid powder (cream of tartar in the spice rack, lol) during the iron/ copper initial melt, then lye powder for the aluminum drop. The thermite idea doesn't really have legs, thermite requires an abundant oxidizer, and there isn't one in the crucible. Mild steel might actually be a better choice than scrap cast iron due to the far lower carbon content, and lack of alloying. Casting iron tends to be loaded with trace alloying agents to improve mold filling.
@ludditeneanderthal One other concern that just occurred to me is that iron and copper aren't terribly miscible - it could also be that the dross is just iron being rejected from the melt... but again, just speculation. A measurement or two would be in order to help sort this out.
It has been known for a VERY long time that iron and copper do not form an alloy, in other words, it is not possible to melt iron into copper or copper into iron, the result is more of a non-uniform mix rather than an alloy. Adding aluminum to the mix doesn't really solve the problem.
A quick google search seems to be turning up a lot of information to the contrary... just one example: www.azom.com/article.aspx?ArticleID=7853
www.quora.com/Is-there-an-alloy-purely-made-of-iron-and-copper
Interesting exercise! I used to be the electrician in a foundry that specialized in stainless and hastaloy casting for pump housings and propellers. The temperatures involved are pretty awe inspiring!
Cheers Gary, I just Googled Hastelloy, seems like a very complex metal judging from the ingredients. I bet you need some serious heat to combine that lot. Cheers Andy 🍺
I have a character in my books who uses a bronze sword. This would be the absolute idea material for it! Brilliant! Thanks for all your effort in bringing this creation to life!
Thanks Mitch 😎😎😎
I'd love to use some of that for guards and pommels on knives
I cross-posted this to a hobbyist knifemaker group on the book for faces. At least one other member of the same group watched both videos, and I'm hoping it stirs up some interest.
I'll share a link in the groups I'm a member of
Thanks Lawren, although I don't think this is so new. Another subscriber pointed out a link with almost the exact same composition of metals. I changed the title, description and thumbnail to reflect this but can't do much about the video content now... Don't want to lead anyone up the garden path.... Cheers Andy 🍺🍺🍺
lol insect was drawn to the light of the glowing ingots and burned up
Looks like some nice grain refined aluminum bronze. Tough stuff for sure.
Pouring with that unsecured handle makes me cringe.
Yeah I need to bolt a bar over it, it doesn't grip the crucible like it used to... Cheers Andy 👍👍👍
My pouring bar has an open ring around the crucible instead of a closed one. This way it allows the elasticity of the steel to act at gripping the crucible better, and have never had any issues with the crucible coming loose even with heavy loads and pouring up to a 30% downward angle.
I was having anxiety watching the last pour. Lol
@@MeltandCast When my uncle worked in a foundry, one of the guys was doing a pour when the bolt broke and the red hot metal went right in his boot. They called him webfoot after that.
Yeah I almost want to scream every time I see it, though I am used to 200+kg pours
Lovely looking alloy does it behave any better on the second melt .
A small percentage of nickel will greatly reduce the brittleness of all aluminium steel alloys.
Do you have any numbers for comparison as to hardness ect?
That looks like a tough beautiful ingot you've made there...I'm just beginning to do my research and make a forge...that little ingot would make a nice set of bolsters and pommels, great video and very brave of you to jump right in there like that.
Thanks Daniel, glad you enjoyed it mate... Andy 🍺🍺🍺
I think you should take two pieces from each batch and melt them together. I think that would make the mix of metal become more as one metal.
All 3 ingots will be given away soon. Hit the bell so as not to miss the give away... Cheers Andy 🍺🍺🍺
Meltand. Cast You could repeat the second process that is on this video then combine to ingots of your third and first times see if that will fix the inconsistencies of the ingot from your first attempt
I have a possible cure ...
DIY SODIUM SILICATE.
Silica Gel Crystal Kitty Litter and DRAIN-O crystals.
Try adding Gypsum, PlasteroParis, or fireclay.
BUILD YOUR INGOT IN ANY SHAPE....
CAST SOME VERY USEFUL BUSHINGS WITH A SHOULDER ...
Methinks you can werk the idea.
Interesting, I'll suggest it to Daniele. Cheers Andy 😎😎😎
I am very Impressed with your Furnace
I'd like that in a frying pan
You like the taste of copper in your food?
@@dwightehowell8179 Never seen copper pots before?
@@dwightehowell8179 I've seen cook ware made of all three of those materials.
Bad plan. All copper cookware has an internal coating of nonreactive metal on the cooking surface. Continuous use of pure copper cookware can give you heavy metal poisoning. I don't know anything about the properties of this alloy but I wouldn't make cookware out of it until I found out for sure it was safe.
@@Mouse2379 I'm pretty sure those giant copper sugar pots they use to boil sugar to make candy have no metals other than copper in them. As they say that they are 100% unlined copper.
Love it Andy, can we call it danmacium? After daniell and your MAC channel? Great video mate
Haha cool name, but I think Daniele should take the credit... I'm just following instructions hehe. Enjoy the weekend mate... Andy
It is an interesting mix. With last weeks video, I was thinking the temperature was so hi to melt the cast iron that it caused the aluminum to burn or something and most of it was the dross.
Such a beautiful color when you cut it in half. It will be interesting to work with.
Thanks James, it was the magnesium content in the aluminium last week... It's not supposed to flare like that. Cheers Andy 🍺🍺🍺
Very interesting and great video! The second batch looks promising. appears to have a lot of surface tension when liquid? wonder if a lost wax vacuum casting would perform? what model temp. sensor are you using? If possible, show a hacksaw blade and drill bit for machinability? There is so much going on there with the addition of the cast iron, Wow! Thank you, from Pennsylvania! Subscribed!! :)
Cheers for the sub James, Yes the pour was very thick and solidified very quickly so I doubt you could use it for lost wax casting. The temp gun is a Testo 835 T2. I'll try drilling and cutting next time... Thanks... Andy 😎😎😎
There's many different aluminum alloys. It would have to be 1000 series to be "pure" aluminum. Your first cast you were thinking it was 5000 series and by the reaction, I think you were right. I think 4000 series would react the way this did but it has Silicon to lower theelting point and make it flow and it's primarily used as welding filler wire. It would be pretty easy melting in tig or mig welding wire that's 4043. The thick stuff may be aluminum that isn't mixing well for whatever reason. I'm only hypothetical in my thinking here and trying to help. 4043 welding wire is probably you're best bet
Thanks for the extra info Scott, I don't have any filler wire. I do have about 200m of aluminium core mains cable though... any good ? Cheers Andy 🍺🍺🍺
I wonder if he’s trying to get you to make thermite
I'm wondering if a frying pan made out of this bronze would be superior (and non-poisonous) to a cast iron pan? Have you any sense of how it conducts heat or if it might oxidize at 500 F ?
What marvellous cookware might it be, perhaps even non-stick and attractive. With its iron content it may work on induction stoves. This could be your million-dollar baby.
Well it definitely wouldn't break if you dropped it, that's for sure !!! I would guess with all that copper it conducts the heat quite well. Apparently you need 1100C (2012F) to remelt it, i doubt much would happen at 500F... Cheers Andy 🍺🍺🍺
"I hit thousand subscribers recently" this video is 2-3 days old (9th Jan to 12th Jan but time zones) and your at 3.5k subs at this point, the recommendation gods must be with you (that was also how I got here by the way)
Well done and hope it keep going.
Also really interested in this potential new alloy, would be awesome if you could test it's electrical properties.
Sadly I don't think this alloy is 'new' just a variation on things that have been done. I'll need to make some alterations to the descriptions and thumbnails later, don';t want to mislead anyone...
I know my channel has just gone mad, went from 1200 subs to 3.5k in a few days, totally mad !! Really chuffed. Thanks for your kind words... Andy 🍺🍺🍺
Watching foundry operators feet around 5 min 30 sec mark (stripped shoes) and stripped jogging pants... Thinking... How to be slavic??
Yeah, proper oldskool me... hehe 😜😜😜
What is the difference between a heterogeneous mixture of metals and an alloy, if any? Chemical bonds, I'm assuming.
But I find it hard to believe this hasn't been discovered before. What happens when it is reheated to temperatures that would normally melt aluminum bronze? Can it even be forged? What are the properties when annealed or tempered?
I am very curious and fascinated by this. It looks beautiful.
Thanks Memespace, I've no idea mate, I'm just a dude in his shed playing with molten metal.... I have no training in metallurgy. The recipe for this was given to me by another subscriber. I'm just trying to re-create it. Cheers Andy 🍺🍺🍺
Nice
I just did my first alumi_bronze was just going for a nice gold color
95% copper and 5% aluminum by weight came out great for the fake gold coins I’m making for my wife’s board games
Aluminium bronze is a lovely metal, and reliable too... great idea for the board games.... That's got me thinking... Cheers Andy 🍺🍺🍺
I have seen your first video on this alloy, and immediately had the idea of making a watchcase out of it. Back then I was wondering how I could get my hands on a small piece of that alloy. Really looking forward to the giveaway.

PS: defenetly got a new subscriber!
Thanks for the sub Kurt.. Cheers Andy 👍👍👍
Awesome and unique for sure Andy. Don't be afraid to to use extruded aluminium. Extrusion is just a formation process just like casting. It can be many different grades. The only way to be sure is if it is marked by the manufacturer. I can't even scratch the surface by leaving a comment. I did send you an email on the subject
Thanks Relyonno, just found your email... Cheers Andy 😎😎😎
I'm so fascinated by this, surely sticking around for more. We really need some way to know if all that iron alloyed in the end result. This could be just a refined form of aluminium bronze, like everybody is saying. But it sure does look promising.
F st and Luckygen made some interesting comments... Carbon, graphite and copper just don't behave too well with each other... without going in to too much detail, they are an incompatible pairing which is why there's so much waste and prone to spots. It might never work "well", sure you can make it... but you could perhaps make something better, with less work and much more reliability... Still Daniele's recipe is out there if anyone fancies it.... Cheers Andy 👍👍👍
Amazing product! It would be great to have the possibility to try it! I'm a knifemaker and it would be very interesting to test it's propriety. I think it would be a perfect metal for guards
Cleans up really nice for a 2nd 1st time pour. Looks to be a very interesting material, think i need to dive into some books to understand the aluminium's reaction in the cook, and the effect it has on the final structure. Thanks for being that chap who likes to try new stuff.. Joy to watch, very avant-garde! Be very interested to see what can be done with it, cast or Forge worked, new stuff is grand lol
Thanks QziQza, I really appreciate that mate, very kind of you. Best wishes Andy 🥂🥂🥂
Just found your channel..thank you tube algorithm! Amazing content fascinating metal. I wonder how easily it could be worked. Keep up the great content.
Thanks Westwood, really appreciate it mate. Cheers Andy 🍺🍺🍺
So the tensile strength is fairly high. Nice. I'd be interested to know if you could make dagger or long hunting knife out of it. How well would the super hard strength of the edge would hold up. (Not a metals person, even what I said may not have made sense. But' I'd still like to know how well the alloy there, would make a small hand weapon from. )
The end result was probably similar to aluminium bronze. So it should be ok, although regular aluminium bronze would be a lot easier to make... 😎😎😎
Very interesting vid. You would do well to put a slider on your pouring shank. My heart skipped a beat when the crucible shifted during the pour. I wonder how the metal would perform if you sliced up and remelted the first ingot you made. Maybe not so much loss on the second melt? Also, you might want to experiment with the making of master alloys of aluminum bronze which is then added to the molten iron.
Interesting approach JT, I might try that someday, I'll tell Daniele too... From some of the other comments though it may not be a feasible project. Lovely ingots but lots of waste resulting in an unknown and inconsistent alloy at the end... Perhaps others will be willing to try this one out. I didn't plan on spending too much time on this... Thanks Andy 🍺🍺🍺
As much as I appreciate a giveaway I don't think you should give these to viewers. It would be better if you would send them to some other youtubers who are into metal casting, blacksmithing or metallurgy in one way or another, we would learn more about the properties of that alloy and it could be nice boost of viewers for you and other channels.Also you should try to contact FarmCraft101 he was recently casting a bronze cannon and he did a lot of tensile strength tests, maybe he would be interested in testing your sample
I'll make another batch of ingots later, once I have contacted some other TH-camrs to get some tests done. People have mentioned a few who might be able to have some fun with this metal... Cheers Andy 👍👍👍
I think you are creeping up on the recipe/technique that will work in your furnace.
Cant wait to get a chance to win one of these ingots.
I have a jambiya build i will be making a video of, and a groovy alloy would make it just so great!
It's not perfect, there are losses of about 30% on this pour, but the ingots sure look good. Just hard to say whats actually in the ingots after you account for those losses. Cheers Andy 🍺🍺🍺
It's certainly an interesting alloy, has a wonderful gold sheen to it. I think it might be something that has a very short window for casting though, it looks like it looses heat incredibly quickly with how quick it thickened up. Your first attempt though, I'd like to see a remelt and mix on it, see if it will blend a little better, a comparison between your accidental alloy and the actual alloy would be interesting, see if that magnesium makes it tougher or weaker. Either way it was certainly a light show.
Might be a good heat sink material, then. If the conductivity stays close to as high as copper, this may be a fantastic wiring option!
Just a thought.... maybe take a trip to your local auto repair shop and ask them for the chips and shavings from when they resurface brake drums and rotors. Maybe it will help during the melt by adding it as you go to get a more blended result. Greetings from Phelan California.
Thanks Augie, much appreciated... 🍺🍺🍺
I think the Canadian Mint uses this alloy in making some of there coins
Does look a bit like a new loonie, doesn't it?
