About 20 years ago , Dr. Gorny developed a magnesium alloy that was stronger than 6061 aluminum and got it to not catch fire.
Really?
yes
@VHTF_ Yes, I cut the samples for him on a lathe , it machined like Brass, very easy. If you tapped it again steel, it would ring , not a dull sound like magnesium. It would extrude faster than aluminum.
Very interesting properties.
@@user-lm9pu3sq9d How the fuck?

Ah Magnesium the metal that burns so hot Lithium looks like a birthday candle.
Yeah, but actually catching it on fire takes more effort than people assume. Especially if it's an alloy.
@SikerMinecraft BMW engine are made with magnesium. They catch fire all the time.
@@nengyang1895 Well building an engine block out of it is just plain dumb. A car frame is a different story.
@@SikerGamingmy father was a shop teacher that had a foundry class (they cast aluminum and brass), he still remembers the day one of his students mistook magnesium for aluminum and nearly burnt down the school.
@@SikerGamingFortunately thermal runaway in a large lithium battery pack provides all the heat and even initial oxidiser needed to ignite most metals that readily burn.

In the 1970's I mowed lawns with a Lawn Boy that had a mower deck made of magnesium. They were ***much*** lighter than steel deck push mowers and lasted a really long time. When we replaced our venerable old soldier I took it apart and cut some chunks of the mower deck off and *by hand* ground up large mounds of magnesium. That fueled my "energetics" experiments for years with my own raw materials and boy HOWDY that sho'nuff do burn GOOOOD... We used to do that sort of stuff as kids. Now they would call you the "T" word and law enforcement would be involved and you would never have a sense of discovery.
Aaa yes, calling curious kids terrorists. The favorite pastime of Karen’s the world over 😭
ohh, terrorists. i was thinking of a different one and was confused.
Weird, I grow up in the 2000s, and my dad brought back two slabs of magnesium and I would get shavings and light them on fire.
Made homemade fireworks as well and would toss them into people’s backyards that were partying on 4th and we’d hear a massive BOOM and chaos would ensue.
Also tossed them in sewers and that made a loud BOOM.
I was able to do this as a kid in 2008-2012 era
Ah yes just like the thrill of discovery when mixing gasoline with foam. No one has ever suffered adverse effects from such a joyous and studious pastime

About 15 years ago, I read a report on vehicle light weighting by Lotus. They said that the economic value of removing 1lb from a car was about $3. At the time, removing 1lb from a commercial aircraft was $1,000 and removing 1lb from a satellite was $10,000. So there is not a huge economic driver for the automakers to use light weight design. Some of them realized that light weight is key to vehicle performance though, and that made light weight design more valuable. The Mazda RX-7 (FD) had all aluminum bodywork. Some Miatas and WRXs have aluminum hoods to help move the center of gravity rearward. An important design concept that I think is too often ignored is that low density materials can often result in lighter, yet stiffer structures. Stiffness of a section of material is a function of its thickness raised to the third power. So for a given mass of structural material, the lower density one can be thicker and will make the stiffest structure-- assuming you can actually fabricate the material into that structure. Magnesium rivals carbon fiber in density, so I see some applications where a low density metallic construction may be an advantage over the composite construction. One nice example of this is XTR mountain bike brake calipers. A cast magnesium caliper must be far easier to produce than a composite one would be.

Been making aircraft parts out of magnesium alloy for decades. The problem with magnesium is it loves to corrode. That of course isn’t an issue for a car manufacturer who would love you to need to buy a new one every 10 years.
Also heat cycles are supposed to soften Mg. Air cooled Beetle engine blocks are Mg. While rebuildable, a rebuilt block can't get as much usage before the main bearing journals lose roundness and alignment.
To your point, VW was supposed to have applied some sort of protective coating to the blocks. I think it was yellow. I never saw it in person meaning it may have worn off after decades. Those blocks tend to cover themselves in oil for self preservation from corrosion.
As soon as battery capacity’s quadruple manufacturers will stop caring about vehicle weight again
Current battery chemistries have nowhere near enough headroom to double, let alone quadruple, and I've basically been waiting my entire life (30+ years) for something to dethrone lithium.
I'm more optimistic about battery technologies which are LESS energy dense, but also lower cost and toxicity (Sodium), given those actually appear to be coming into production.
@@mazeofthemind560 it seems unlikely that we wouldn’t be able to make batteries more energy dense now that there is a huge amount of demand from EV’s I doubt Lithium Ion is the end
@@daundredemars5028 So I'll take an L here, upon investigation there are absolutely notional battery chemistries that can achieve 4x energy density (by weight, specifically) to Lion. We could debate how feasible or near term they are, but that wasn't your point.
Its also worth noting that 4x Lion still isn't within spitting distance of gasoline (250 Wh/kg vs 12000)
That said, I feel very confident that if auto manufacturers are feeling pressure to innovate on structural engineering and materials for GAS engines due to mileage standards (and they are), they aren't going to stop caring for a 4x future source which is still less then 1/10th the energy density.
Good luck with that lol
@@ghoulbuster1 we have octupled batter density since 2008? Why couldn’t we quadruple it by 2035?
I would've loved to see an infographic of the strength to weight ratio for the new magnesium alloy compared to steel and aluminum, but generally this was peak TH-cam 👌🏻 thanks
I also want to know
Look up "Material Strength vs Density Chart", the Cambridge and Ansys ones are good
I'm a simple man. I see a video with 13:37 and I click on it.
Very informative.

Lawn Boy was making mowers with Magnesium decks in the 1960s. I also remember my brother’s Chevelle SS having Magnesium wheels in the 1970s.
Imagine you get into a fiery accident and your entire car starts to glow like the sun.
electric cars already do that.

I am doing my masters in environmental engineering and researching magnesium based materials for decontaminating soils and water. it is showing amazing qualities that i would not have expected at all better than even conventional materials
It turns out that stamped aluminum car bodies do exist, they just never caught on at a large scale. The reason for this might be that, despite improving fuel efficiency, they also increase cost, and for gas cars, nobody cares about fuel efficiency. The high pressure die castings should have broader appeal, as they decrease the cost of the vehicle, in spite of using a more expensive material, thanks to large reductions in fixed costs
Pretty sure ford uses for f150, not nothing as best selling truck in the country
@@patrickmanasco5905body panels not structure.
Using Aluminum mean the item will have a finite life. Aluminum has a finite fatigue life, were as steel is infinite (assume stays in elastic zone).
My 1990 F150 has 2 small spots of rust on body and after 600k miles. I highly doubt it would have survived if the frame was Aluminum.
@@bowez9 You know airplanes are pretty much entirely aluminum right? Handling 30-50k pressurization cycles. So are fighter jets, dealing with insane forces. An f-16 has 1/10th the rated hours as an airplane, but that makes plenty of sense. As long as the design is properly matched to the load and use case, there is no inherent superiority of steel.
@@garrettmillard525 and that us why they get required after so many hours, and eventually decommissioned.
Ask yourself how many oscillation a vehicle under goes driving down the road. Evert bump counts as 2, as it loads and then unloads.
@@bowez9 Do you understand what fatigue life is? The number of cycles it can endure under a given stress. At stress amplitude S, 10^5 cycles. At stress amplitude S/2, 10^8 cycles. At amplitude S/1000, which is what each bump in the road is, the cycle life is, for all intents and purposes, functionally infinite. Castings and extrusions can provide incredible stiffness and strength, and there is zero worry about corrosion. Your 600k would not be possible in less favorable environments. You must not have much experience with aluminum extrusion if you don't know how enduring it truly is.
Yes, off-roading, or 18 wheelers, sure, steel is entirely sensible. But, just like aircraft, it is entirely possible to design structural aluminum components that will entirely outlast other components. Fuselages don't get replaced. Steel chassis sure do, though...
I work in the archery industry, there's a bow company (Xpedition) that is using a magnesium-aluminum alloy to make compound bow risers that are about as light as carbon fiber ones.
Magnesium in automotive isn't new, infact it's quite old. Even old alloys were implemented as engine blocks. Now saying corrosion is "solved" is a misnomer. In comparison to aluminum, the best alloy of magnesium is still quite reactive. The challenge is more on the design side. Metallurgy can still be improved, but the impact is where and how you use each metal in a vehicle. That's not to say the increasing demand for lightweithting isn't a new shift in industry. Indeed, new developments in casting techniques and Metallurgy will allow the implementation in good designs. I can easilly agree with your assessment of production. However, I think alot of people forget the importance of market circularity in emerging demand. Good design and Metallurgy should consider the requirements of recycling for recovering already extracted materials.

@@remcovanvliet3018 wooh that nothing burger is really tasty do you think I could get some mustard to go with it?
I’ve seen a couple of your segments now and I like your insight. The notion of harvesting Mg from desalination brine is extremely interesting, especially since sodium batteries are reaching mass commercialization and such brines would seem to be a great source for that, too. This potentially solves a multitude of problems at once.
Can the brine also be used as heat battery material (molten salt battery)?
Mg is also the byproduct of table salt production because magnesium salts attract moisture so they have to be removed.
My academic advisor in university is actually the person who developed the YSZ process mentioned at 7:38 lol

Really a treat to come across an informative video that’s eloquent, logical, concise, well structured, thoughtful and well researched while still being laid back enough to be pleasant to watch.
I've had old vw beetle engines with magnesium cases, and I still have a 1977 Bultaco motorcycle with magnesium engine case. no real point to my comment just feeding the machine for your excellent video!
I've worked on magnesium chainsaws
The only thing that im worrying about is the price of the alloy , since yttrium and calcium metal is expensive
Electric vehicles with Magnesium component already exists. Best real life example to me is the EUC Veteran Lynx, it's hands down the best all around due to it's lightweight body when compare to power delivery and size. And the magnesium shell design is the key to that. Thx for your time and dedication you put in your videos, always top content IMO.
They do exist, but the size/weight limits for existing injection techniques are pretty low. I suggest having a look at progress IDRA is making in this area, using a "thixomolding" magnesium slurry (apparently it works better than fully liquid magnesium) th-cam.com/video/wbXGplRrCqY/w-d-xo.html
Mercedes: "Yeah I'm not falling for this one"
People have long had the idea to make cars entirely from magnesium, but there is some reason, technical or financial, that has held the idea back. In the 1930's Dow made prototypes that they marketed of a car made from "Dow metal," which was magnesium, including the frame, body, engine block, etc. They derived the magesium from underground water.
Apparently the amounts of magnesium in seawater are enormous. So you don't need to mine it, but obviously theres a cost of extraction.
The original VW beetle type 1 engines had magnesium cases. When i was a kid any aftermarket wheels were called "mags," because sometimes they were magnesium. Bits and bobs of racing vehicles would be made of magnesium. There were bicycle frames in the 80's of cast magnesium (not very successful), and now there is a small number of bike frames made of aluminum - magnesium alloy.
Magnesium has already been used a lot in aircraft parts for decades.
The Germans were some of the first, they used large, forged magnesium parts. The press used to make them was taken to the USA and operated for over 50 years, producing critical parts for American aircraft and weapons.
@@Shaker626What’s the source for this? 90% of the time German WW2 technology comes up there are huge caveats
As long as it stays a solid, it’s very safe
I'd like to see some numbers on how much weight will be saved and how that will translate into EV range.
They could get CaCO3 *and* Mg from seawater using biorock electrodes. The energy cost is low (cents per kg); unfortunately it's a batch process, not continuous.
I will go to my grave with the assertion that the Volkswagen beetle was one of the most well engineered vehicles almost 80 years ago. Yup, it had a magnesium engine block as just one of the many advanced techniques employed in its design and construction.
Liked the ASUS Expert Book made from aluminium magnesium alloy. Durable and better than any plastic notebook, even your rubberized one Lenovo.
Thinkpads are also magnesium, (under the rubber).

While following troubles of B Bonner's ranch high in Andes, alternate land use idea: hi-altitude desert, near equatorial Pacific coast, high solar radiation, sea water not very distant, but much lower elevation. Speculate turbine pumping ocean up to solar farm, processing there, purified water goes back to low elevation recovering potential energy with turbines, then use fresh water in agriculture etc. Or, transmit high-amperage power down to coast for water processing.

Solar is NOT the cheapest energy ever produced! Typically, the cost of mining, manufacturing, transportation of solar panels is never completely accounted for. Additionally, subsidies are not considered when calculating the cost, nor is depreciation or degradation that begins on day 1. Efficiency of the panels is based on perfect atmosphere devoid of weather and pollution, and latitude is never considered. Putting industrial solar arrays in the best locations typically costs too much due to power transmission losses.
Industrial solar both grossly under produces power when needed and over produces power when not needed. There is no general economical way to store sufficient power in the foreseeable future. Solar panels do work on site in off-grid applications, but so far are dismal failures in large scale applications.
Modern nuclear plant designs are the foreseeable future of grid energy, especially modular molten salt designs that are demonstrably failsafe.
But solar is safer and cleaner than nuclear. The storage solutions hopefully will improve. In large scale solar plants, the investment pays for itself in a matter of three years, though.
@@casandraa.9837 That is what they want you to think.
Though few want to live next door to the traditional light water reactor that was originally developed for nuclear powered submarines, they are still statistically the safest of all current grid power solutions. Molten salt reactors are even safer because they can't blow-up or meltdown. Search on thorium reactors.
As far as clean energy goes, research the mining and manufacturing of solar panels. You have to dig as that part is heavily censored. Also, solar panels have a relatively short life and cannot be recycled. Checkout early California solar farms that are gathering dust as the landfill costs are too high.
The modern molten salt reactors being worked on now will be even cheaper than solar as once a design is perfected, they will be mass produced in currently idle shipyards.
How could they not be accounted for? The panel manufacturer isn't selling them at a loss, nor is the distributor taking a loss, nor is the installer deploying them at a loss.
Just check rooftop solar prices at your local installers, and calculate your LCOE over 30 years. You can even put a 30% discount on their claims of energy production. You'll find that the LCOE is not only lower than grid electricity, but also lower than the grid fees
The USA may be an outlier in this sense, as their extreme overregulation makes rooftop solar about 3-4 times more expensive than in other developed countries, but commercial and utility solar in the US does not suffer from this
California already covers 25-30% of its evening peak power demand with batteries, charged from solar, about 6-7GW, and companies are already molding their processes to be able to use the solar power in instantaneous consumption, making batteries unnecessary
This isn't something new, either. Arc furnaces have been designed to run on off-peak power for a century, just that the off-peak has moved from night to day
The 2nd European solar boom is happening without subsidies
@@SizeMichael Apparently, you are not aware of the abundant solar subsidies across the US, nor accounting for power degradation from day 1, weather failures, large transmission losses from grid solar farms, habitat losses, nor end-of-life disposal costs.
You also don't seem to comprehend that solar power is not constant or reliable, requiring traditional power plants to be available to provide up to 100% of the power when solar power is not available. Powering-up a backup powerplant is neither quick or without substantial cost just to start providing power to the grid. And, don't forget the investment cost of just having a full-size backup powerplant sitting idle. We are closer to fusion power after over 50 years of intense research, than being able to economically solve the grid storage for solar power.
Solar power works well for most off-grid applications, and nearly all mobile applications, though storage will be the most expensive part and capacity is limited by money to invest in solar. Except for off-grid and mobile applications, solar is a waste supported by huge amounts of taxpayer dollars funneled through a multitude of programs and schemes.
Modular molten salt reactors, particularly thorium based, are the only viable future for grid energy.
@casandraa.9837 false. Solar produces far more toxic waste by-product/kwh than nuclear.
Nuclear power is the only viable solution to climate change that doesn't involve strip mining the entire earth in order to "save" it.
Thank you for putting this together.
I have never even thought of magnesium as a material to possibly make more efficient components for vehicles! Thank you for enlightening me

I agree with the feeling, but from a data perspective, granted *citation needed* obviously, (Animal) Agriculture is more to blame than Housing itself.
Especially growing water intensive crops for CAFOs and such.
It's true that the concerns of scarcity are only a thing because of agriculture, I just find it funny how many people will move from a water rich part of the country to a water poor one, and then act like water availability is suddenly an issue for the country as a whole
I remember reading about a new new magnesium alloy in something like 2021, was wondering when TH-camrs would find it.
I was convinced that magnesium had become a more available material recently. Especially in the manufacturing of small and sometimes complex parts.
There are a few gaming mice that are made of magnesium now. At least 5 that have been released so far and a 6th that should come out soon. I knew something had to have changed for so many to have come out so quickly.
The fuel efficiency analysis at the beginning was on point
For the stamped aluminum question, I think the biggest draw back to it is aluminums lack of malleability and how brittle it becomes at the bent points.

Making fun of US ✓
Magnesium ✓
Dow's process ✓
Few things that might need to be mentioned here:
Magnesium alloys can be thixomolded - injection molding using semi-liquid magnesium, gives you better part quality and uses less energy.
Magnesium alloys have very good noise and vibration dampening properties, which would make cars not only lighter (Mg vs Al ~30% lighter) but quieter.
Mg is also 2% of earth's crust (Al 8%), so it will likely drop to similar cost per kg as aluminium or even lower since it's extraction can be easier and cheaper, which means it will be a lot cheaper in cars, since you'll only need around 70% of material for the same strength and rigidity.
It's nice to see new alloys being actually resistant - first bikes, wheels and frames made of magnesium were extremely prone to cracking.
As for weight/regulators bit - it's not true that manufacturers just didn't care about making cars lighter, but because ICE's are very limited in their efficiency and design, weight wasn't really a serious issue. If you calculate how much rolling resistance (from weight) a normal ICE has, you'll be astonished it's almost nothing in average driving conditions.
You also can't go nuclear on aerodynamics like in EV, since your engine bay and tons of components will still need extremely good cooling.
Mg/Alu components just aren't necessary for normal ICE cars, since there is very little to gain there. For EV's it's different story - you lose 200 kg, you can add 200 kg of batteries with no net gain.
Things like thixomolding are just a really good side effect of this evolution.
Also EVs are getting cheaper to produce than ICEVs, and cars are mostly competing on price.
We don't have aluminum cars because of the stiff brittleness. Hit a bump too hard or get in a fender bender and you could have a giant crack spread from one end of the frame to the other. Also aluminum is way harder to weld. I have similar concerns for magnesium.
Well the supply part is dead easy, Magnesium is the 4th or 5th most abundant metal in the earths crust, and makes up a large percentage of the mantle. Its everywhere. Its just really hard and energy intensive to make into a metal.
The age of Magnesium. Finally. A world without zinc is possible 🎉🎉🎉🎉
Magnesium has been very common in rifle parts for a bit over a decade now. It was mostly used for raceguns and competition rifles for weight reduction where polymers weren’t strong enough.
the question is what will be the impact on leaving thinks when we take out tons of magnesium out of the water in 100 years
We have ready tried magnesium, we used to make everything from magnesium, lawn mower decks, household appliances, door nobs and so on, but we stopped ... because it sucked, I would seriously invest in the idea that these new alloys and techniques aren't nearly enough to make up for magnesium's downsides
Did you watch the vid? The only application for magnesium told in the video was Electric Vehicles. The "age of magnesium" the video is talking about is the simple idea that as of right now magnesium extraction is really shit and makes it more expensive than it should be... so right now is the time when there's a demand big enough (reducing EVs overall weight) to justify increasing the efficiency and efforts of extracting magnesium. Note that the use of magnesium in EVs was only as structural parts, likely those which have minium expusure to wear, corrosion and heat. (Also, the vid mentions that modern magnesium alloys don't catch on fire)
TL;DR: Magnesium does have downsides but for this specific use-case, it's worth it economically to use and this in turn makes it worth it to extract in bigger quantities, which will potentially make it even more worth it, and this series of events could start "the age of magnesium", as clickbaity as it sounds.
Another good recommendation by the algorithm. Perhaps I treated it too harshly.
I worked in magnesium diecasting years back now. Yes, you can get magnesium less flammable, less being the key word. There are a lot of problems with doing that through. Mostly, the more aluminum you add the harder it gets to work with the alloy in a manufacturing sense. The alloys tend to be thicker and sticky which clogs the pumps needed in the diecast process. There is also the problem of the metals properties in general. It is stronger then aluminum but more brittle. That is how we ended up with some newer alloy as the part we were making couldn't survive crash tests without shattering, (no, i am not going to get sued for telling you any information on the actual part and really you don't want to know anyway). So we were made to use a different alloy that was so much harder to work with. Although less flammable once it was on fire it was still burning magnesium and all of the fun that goes along with that. The amount of dross in the molten metal was ridiculous and no one wants to be the guy standing on top of a 500 gallon pot of molten magnesium dipping out dross while their boots melt. The alloy was sticky and clogged every pump it went through. It also would stick to the die and cause buildup on the die that continually stopped production. Basically what i am saying is it is a really great metal that will probably never actually be used the way this video is suggesting. The finished products would be great but making them in mass is the problem, you can make a few a day real easy, it's mass production that i don't see being worked out. As for high pressure diecasting with magnesium, well almost no one does magnesium diecasting in the U.S. because the normal process so very dangerous, now make sure that explosive metal you are working with is put under intense pressure and things can go bad real quick. Had a press malfunction on my day off, die closed way over pressure and that caused water to get through into the die during a shot. This was a small part 1 and a half pound pour. The ram shot and a fireball hit the ceiling and blew under all of the gaurds, operator ended up with only very light burns. The explosion blew a hole through the die face the was the size of a silver dollar and it did it instantly, (when i say blew i really mean melted). Not sure if anyone out there knows about diecasting and tooling steel but we are talking about almost the hardest steel on the planet, makes iron feel light when you pick it up. Now imagine a malfunction when casting a 500 pound frame... Maybe i'm wrong and they can make it all safe which would be a very good thing, as for myself, i don't work in diecasting anymore because that is dangerous work.
As far as I know, the process will be thixomolding in the case of IDRA. The dangers you describe are why traditional high pressure die casting this stuff would be a mistake. Thixomolding helps a little because less of the process exposes the metal to air, because the partially molten metal is not as hot and less of it is hot at once, and the piston pump injection supposedly solved the pump-clogging thing. Its also more automated, putting fewer workers in harm's way. And even then there are challenges that might not be solvable.
@@themogget8808 being exposed to air is far from the worst problem, it is being exposed to the water that you need in the process to cool the doe down that is the big problem. You have to have water pumping through your die to cool certain parts while leaving other parts hotter so the metal flows properly across the die face. Under normal operation this is fine since the water is flowing inside the die and never comes in contact with the surface of the die, but stuff goes wrong and you can find videos of water and meg meeting here on TH-cam. If there was a issue under high pressure while casting a large part then there is a good chance automation is going to be helpful as your whole factory is gonna be gone. I'm just a low level button pusher though so maybe they can work around all of the problems.
My skateboard trucks are a magnesium alloy and the difference is incredible.
My gforce dog box transmission has a magnesium tail shaft housing with aluminum main housing. Some transmissions have the full case made from magnesium.
Welcome to the age of Magnussen
What a video! I can’t wait for the next one 👍🏻
I helped make magnesium impellers for Toro leaf blower / leaf mulch vacs from cast magnesium. The biggest challenge was balancing them for the high RPM with a plastic press in hub. Safety concerns were from dry machining scrap and grinding powders.
Excellent vid m8 will be lookin into companys doing this work for sure
6:10 we all gonna be mineral deficient with this one🗣️🗣️🗣️🔥🔥🔥
I wonder if the "newly" discovered salt cycle (magnesium is in a salt form in sea water, like you explained in the video) will play a role in calculating the environmental impact of using magnesium?
Great humor along the interesting viewpoint!
I don't know why but, "depleted sea water" makes me laugh so much.
Thank you sir! I have a new thesis to develop and research on. I wanna see if I can find a good magnesium business so I can gamble my money on and hand it in to rich Wall Street people on a silver platter.
A great comprehensive insight into this metal, thanks. Just discovered your channel, am curious about your opinion on the "minerals crisis" of the green transition { & business as usual for that matter} & what do you think of Simon P Michaux's work on this?
Al is far more brittle than steel and the work-hardening is more prone to failure. I presume this is why the methods used for steel don't work. You can use extrusions with a regular form that aren't repetitiously stressed, but nothing like how a steel frame is used
Hey man that was a great video, thanks for sharing!
I remember using my magnesium pencil sharpener and chip it for small fire, i think you overlook this huge aspect
He talked about that right at the start lol
