- It's time to reveal which elements this shiny block of metal from my previous video is made of. Link to previous video here: • Exotic Elements vs. Ma...
You guys sent so many guesses that I learned about alloys I didn't know off myself :) Once again thanks to all that participated! The CuBe-alloy seems to be quite unknown but has a lot of practical uses. Beryllium-copper even has the highest strength of any copper alloy we know off!
Closed captions in English and Danish coming soon... - วิทยาศาสตร์และเทคโนโลยี
I respect the fact that you advertised the winning channels along with saying their names out loud, that was pretty cool of you, subbed :)
Luke McShane Thank you for subscribing. That's cool ;)
I like the fact you have Frank Zappa as a DP liked.
Keep with the motto of quality over quantity! Excellent infrequent videos are way better than regular weekly crap so many others do! It's always a treat to find you in my feeds once in a while. :)
Beryllium copper is also used in space and other applications where it might be subject to cryogenic temperatures. This is because it has decent mechanical properties but most importantly it has a high heat conductivity at cryogenic temperatures. This is good because the same mechanism that transports heat, quantum vibrations of the crystal lattice called phonons, is also the same mechanism that transports stress. So it isn't brittle at very cold temperatures.

@@SR-be1is a needle can float on mercury, it also will not wet it so it will kind of repel it.
New video uploaded! This time I reveal what the mystery alloy I showed in my previous video is made of.
And I find an excuse to test a 20 mm shell casing with a magnet...
Hope you enjoy it.
Yep...and the "todesmagnet" at that...
Well when is the closed captioning going to be on???
i thing it was zuconium because if you touch zuconium it will give you nasty smell.and it repal magnet.i have 1kg sample of zuconium
Mad Science 82 1 kg of selenium? That's a nice amount :)
If you have 1 kg of selenium or even worse tellurium, you should be careful touching it or you may lose all social contact because of a bad smell ;)
Well you should watch peraiodic video
Thanks! Nice to hear that you understand my choice.
If I had to upload once a week it would be 1-2 minutes short videos of lower quality... I'll do my best to upload once a month on average. That should be possible most of the year for me. Right now I have so many ideas for videos that my biggest problem is choosing what to do next :)
I would have guessed bismuth, mainly because it appeared to have that slight pinkish hue. But it's also possible that the pinkish hue was just a reflection off of the large copper bar nearby. Apparently I missed the "alloy" description in the original video. That would have precluded pure bismuth.
It is going surprisingly fast although my channel seems to have peaked. Thanks for supporting my channel :)
Wow. Crazy How I knew it was Beryllium-copper since I work on UH-60s We handle beryllium-copper constantly. They are the "Droop stops" for the main rotor blade!
+sipriano solis
Cool! Droop stop is a new word for me :)
I have machined this a few times in my 40 years as a machinist and we machined it totally submerged in coolant.
The mystery was very interesting, waiting for the next one. Thanks so much for promoting my channel.
Awesome videos, glad I found this!
bdbdbd Thanks :) Welcome to my channel.
I wonder what the odds are for that :) In Denmark it is/was also popular to turn the shell casing into a lamp by putting a bulb and lamp shade in the projectiles place.
My clues were getting stronger and stronger ;) Once again thanks for participating!
its aluminum brass?
turn the brass into gold, I know the aztecs made copper turn gold on the outside some how. it was tumbaga
it was also used in handrails back in early to mid 1900's because it kills bacteria. look at some pictures from the 30's at Grand Central Terminal

@@SR-be1is holy shit, after seven years.
Umm, to tell, you i dont know. Sorry about that
Great channel. Did you happen to plan to test the magnet towards cell phones and some bigger electronic things?
I work with beryllium daily. the dust is carcinogenic, yes, but the solid metal is fine to hold in your hands. Also, berylliosis doesn't affect everyone. You can take a blood test to check your sensitivity to the metal.
It's a very pretty metal, though. Until you let humidity oxidize it and turn it gray.
Woof!
Heres to hoping some old brass hammers that I polished the faces of weren't beryllium bronze.
moo. So, is Beryllium the "secret ingredient" to the Zildjian family B20 alloy that is kept under lock and key? They always state that B20 alloy is 80% copper and 20% tin with traces of silver and other elements, what are these other elements that are kept so secretive for all the centuries!?
BigTimeZergRush Look for a "Berylco" stamp on it. That's a very popular manufacturer of beryllium copper tools. If it has it, you're probably already dead.
Very cool as usual. Speaking of unusual alloys used in musical instruments- do you know about argentium? It's a relatively recent silver alloy, with copper (as usual) but also a bit of germanium. The germanium makes it more resistant to oxidation and also improves its tensile strength, which can be increased by heat treating. I've got argentium strings I drew myself on my double harp.

Thanks for the very interesting guesses from you. Some of them were new alloys to me so I learned a little :)
I'm considering what the next challenge should be so stay tuned.

Try to mix 86% copper with 8 % tin and 4 % germanium, this would be like a CuSn8 tin bronze but with total corrosion resistance given by germanium. Don't put more than 4% germanium or more than 10 % tin. If you mix it make a video showing if it has become corrosion resistant or not. I am Kedves Szabolcs from Transylvania, it was my idea to use bronze alloys for watches, but they corrode.
The clue about non-sparking alloy was a dead giveaway, but thank you for the shout-out
wow already up on 10000 subs :D gratz when i joined you had around 300
Great video. Thanks!
One missed opportunity: you could have made a cube out of it for this episode. a CuBe cube
Where did you get an ashtray like that? :D
Did they use to use beryllium in brass hammers? Cause I have some fairly old brass hammers (around 20 to 40 years) and was wondering if there is anyway to tell if it has beryllium in it.
Beryllium copper hammers are available (explosion proof hammers since they don't make hot sparks). I don't know of any easy way of testing for beryllium. Tools using beryllium copper are often marked BECU or CuBe, but I can't guarantee they are all marked.
Not having read anything commented or even able to have the time to watch and going simply by the CuBe I will take a guess and say Copper and Berrium... If not mistaken Berrium is a transitional state of Copper Sulfide or oxidized copper...
I will watch and or read later...
Thanks for the video.
oddly enough my grandpa made an ashtray out of one of those shells but it also has that 20mm as the center of it.
Spoiler alert: The title says "CuBe". "Cu" stands for Copper and "Be" stands for Beryllium. It's a Copper-Beryllium alloy.
I was thinking of some sort of bronze in the beginning of the video and since I watched it turns out it kinda is and kinda isnt at the same time
Looks like a metal mini Charleston chew.
Love your voice, you sound 1/2 loony professor and 1/2 mad Viking. (No offence ;o)
Hehe, I'll take it as a compliment. Thanks for watching.
You are a true tip top content maker. Very pleased to have found you. And it was a complement, of course. (I'm clearer headed today, so not so prone to typing weird stuff)
0:10
if you gave me a picture of this frame and told me to guess ...
i would have guessed cesium (the bottle thing)
My hopes were up when I saw the electromagnetism since silver is the most conductive element I believe
Nice brader
we broke down be in my science class today in protons nutrons and electrons it was lit we used expo markers on the tables
Under 301 yeah!
I got it right! Bismuth and Copperiku!
Your the best :)
you're awesome, i think this is like 5th time you've replied to me or something too :D
It's a terillium-carbonic alloy!
My first guess was Beryllium Copper, I learned about the dangers of machining it in tradeschool so when I saw the gloves and colour I knew it had to be. (Admittedly I'm too stupid to have clued in on the title [CuBe] and expected it to just be a play on words or something lol )
Which metal or Chemicals Repel.Iron needle anyone's answer me
CuBe has has the elements Cu and Be
I knew it when i saw the formula/makeup
I wish it was shaped like a cube
Subscribing..I'm actually only primary 3 but I am very interested in chemistry :)
You should use water to measure the volume of the bar
ahh i thought it was our new German-Alloy! (excuse the pun)
I have billet platinum quantity 16kg and indium 26kg and 50kg
the old bronze alloy?
Damn. I was hoping it would be gerluukaluuk.
wat
gold
I KNEW IT
White gold
It's Helium ingot!
Were do you get the majority of your samples? :S
The majority is from eBay but there also dedicated webshops like smart-elements and onyxmet etc.
Thanks for watching :)
OK, thanks!
Zinc and copper
Subbed , you have some interesting Videos :) QC
Great! Thank you and welcome aboard :)
Which metal or Chemicals Repel.Iron needle anyone's answer me
haha love it! :D
I know it is obvious when I read the title, it’s copper beryllium
I think that I arrived 7 years late...
so little beryllium and the copper color is gone! if there is beryllium in golfclubs , not really dangerous my thought
Make a cube out of CuBe
Or iron and gold
I knew it was "Alama", but I didn't knew English! LoL. Alama=Brass in Romanian.
Pure gold with pure silver now let me finish watching the video
That is netherite from minecraft
It contains the elements
Cu
Be
Bismuth and copper
So it was gypsy gold
It's a UFO fragment from Area 51!!
Copperberrillium
Copper-beryllium?
Phosphor bronze.
With it being CuBe, I would've said Copper Beryllide.
Which metal or Chemicals Repel.Iron needle anyone's answer me
its copper and beryllium
no really
We use to make plastic molds out of Copper Beryllium Hobbing a part into it. An old way to make odd shapes like animals an badges. circa 1968.
*Copper Beryllium.*
I dunno, I got 1 small bead of pure beryllium metal last Christmas (it is 2015 now), but I am still fine. I have touched my bead multiple times with my bare hands.
And because it is iced with copper, that alloy is HARMLESS.
The dust is dangerous. When solid it's not that bad
I tough it was bronze.. so close :(
Galium
Gallium is an element, not an alloy.
(an alloy is a mixture of metalic elements).
Gallium is also silver, but can become greyish (kinda like lead) when impure.. it also becomes a liquid at 29.76 °C.. ie, just above room temperature.
I was wrong too BTW, I was going to say iridosmine or Osmiridium, I wrongly guessed that the alloy in question was a mixture of Osmium, Copper and Gold.
oh well i was close in the fact that it is some what dangerousXD
Isnt that 20mm a .50 cal?
.50 cal bullet is about the size of your thumb
its gun cartridge
Coper and gold
It's beryllium Bronze
I (almost) won! :D
10 year ago-
I said Zinc first, after joking about platinum.
i get firsters, but 4th, gotta be kidding
My son said that it’s gallium
looks like fools gold
beralium copper
Which metal or Chemicals Repel.Iron needle anyone's answer me
Its CuBe
Looks like silver to me.
brass
I thought it was a gold/copper alloy from CPU recycling.
+TheRealTrikein
Not a bad guess. It would probably look quite similar - and be worth much more :)
i was gonna guess a gold alloy. i was way too wrong :D
+Zan Getsu
For me to afford it, it would have to be a very small percentage of gold ;)
Thanks for watching!
Brainiac75 hahaha well even if i had guessed right my channel is empty
I am correct
