The Density doesnt really correlate with properties like hardness. Thats because density is mostly affected by the mass of the atomcores, while hardness is mainly affected by the bonds.

In the 1980's working at British Nuclear Fuels the fuel rods were made from magnesium. On bonfire night they would fill an aluminium dustbin with the swarf and light it. I remember vividly seeing the shadow outline of the crowd on houses 100m away. Way brighter than daylight in a full field and so white.

Congratulations, the.. "white" light is UV light so intense it completely overwhelms any optical sensors. Camera as well as eyes, to see the true colour of a magnesium flame you'd need one of these temperature cameras that create an image not by light emission sensors but an radiation intensity sensory array and translating it into human-conceivable colours by shifting it into a spectrum the human body can sense (like shifting up or down audio tone pitch to make it comprehensible to the human ear by bringing it inside of the human hearing range and does NOT mean, that it's that colour or pitch in real life.. Colours are an illusion anyway. It's all more or less colourless, but due to different light refraction properties of certain materials and surfaces. When you're adding colouring to something, you're not changing the thing, but the way its surface manages to refract light. Without our eyes, everything is grey, "Eigengrau". The "static interference" in our optical nerves humans and therefore silence used to call "black" but actually is a mix of all the different RGB sensors in our retina glitching out uncontrollably but still homogeneously.. except for when you're high and your mind's pattern recognition feature is basically super- and turbocharged with weed, on Nitro with Shrooms and on TopFuel with LSD, having you imagining vague, random outlines and shadows of things in the static.. no matter if the eyes are open or closed. It's a software-problem more than it is a hardware one, so except for filtering the light input in general, like in sunnies or selectively by frequency, like torch hoods, is only semi possible. It's ike the analogue TV static, just in 240k.. 😅 Sorry, I'm more of a car/microbiology nerd than anything else. 🤪

Metals plastically deform by forming and moving imperfections called dislocations around the crystal lattices of the metal. The crystal structure of magnesium is hexagonal close packed (HCP). HCP metals tend to fracture like you saw because there is a direction in the crystal lattice in which it is very difficult for the dislocations to move, so the material will shatter instead of moving as you hammer it.

Honda made a Formula 1 car with a magnesium body called the RA302. Their usual driver, John Surtees, refused (wisely) to drive the car on safety grounds. They put a substitute driver, Jo Schlesser, in the car for the 1968 French Grand Prix at Rouen Les Essart. There was a crash at the six brothers turn and the car ignited and Schlesser was killed. Quite an unfortunate, and worst of all, unnecessary incident.

When forging magnesium, you have a one heat one strike opportunity. If you mess up the heat, it burns. If you mess up the strike, it burns. You need to put it directly into a press with a mold. Heat it, and then press it into the shape of the mold. Do not miss.

This video is so cool to see since I work with these alloys on a daily basis, casting, extruding, etc. I work at a company that specialises in magnesium production here in the UK for all kinds of industries. We make the alloys mentioned in this video such as WE54 and Elektron as well as dozens of other alloys. We've made stuff for Porsche, Ferrari, Honda, and even the apache helicopter uses our alloys. And Alec you're right this material is incredibly difficult to work with and is incredibly dangerous but I really enjoy working with it. We need to use cover gas at all times to keep magnesium from oxidizing when heated, otherwise magnesium oxide gets in and you end up with crap material that lacks the properties required. Basically if you don't want something to oxidise, just take away the oxygen!

If forging magnesium - heat it using inductive heating in an inert atmosphere and also forge it in an inert atmosphere. Burning magnesium is normally extinguished with special salts or dry sand, a D class fire extinguisher designated for magnesium would be preferred. Water can cause oxyhydrogen gas to be created and make things worse.

The "Elektron WE54" Alloy is about 91% magnesium. Pure magnesium would be way softer than this alloy here. Magnesium is soft enough to cut it with a knife kinda like wax-like maybe a bit tougher. More reactive as well. Apparently, the Yttriumin in the alloy gives corrosion resistance, meaning less oxidation/rust and harder to burn it. If it were to be pure %99.9 magnesium I doubt you can put it out with just water even if it's small in amount it would explode. If you like to know here are the contents I found for it. Element Content (%) Yttrium, Y 4.75-5.5 Neodymium, Nd 1.5-2 Heavy Rare Earths 1-2 Zirconium, Zr 0.4 Magnesium, Mg Remainder

Materials Scientist here: Magnesium and its alloys were quite big before and during WW2 specifically in Germany. That was because Bauxit, the mineral from which Aluminium is synthesized, couldn’t be mined and bought by the German Government. Magnesium was seen as the alternative and in fact, Germany became the leading country in Magnesium research, production and processing having its center in Bitterfeld - Magnesium was known as the „German Metal“. After the war, a lot of knowledge was destroyed and lost (some estimate a 60-year-set-back) and researchers are still catching up in a few areas of research. A lot of what was left went to the UK in the form of Magnesium Elektron (today known as Luxfer MEL). The material WE54 (W = Yttrium (5 wt%) and E = Rare Earth (4 wt%) like Neodymium, Gadolinium etc.) is one of the alloys developed in Bitterfeld for high temperature usage. Magnesium and most of its alloys have a hexagonal closed packed (hcp) crystal structure with a c/a ratio close to ideal. This means that there is only a limited number of glide systems for dislocations (less than 5 independent ones at ambient), resulting in a very limited formability and forgability as you demonstrated here! I was somewhat surprised that at higher T, the forgability is also quite low, as at high T more glide systems become active in theory. However, Magnesium has a low heat capacity meaning it looses temperature quite quickly. Due to its low ability to deform uniformly and without breaking, parts from Magnesium are mostly produced by casting like high pressure die casting.

Absolutely incredible work, apparently it took them quite a while to get down the process for welding thin magnesium sheet metal. I believe Jay Leno covered the car on his YT channel, look for 'Bugatti Aérolithe'. It's a fascinating story of a concept car that was shown once or twice in the '30s then lost(thus far), and The Guild started with an original Bugatti rolling chassis and recreated the magnesium body from scratch based on pictures. Their work is second to none.

The Convair B-36 Peacemaker, a holder of many records had an airframe consisting of a lot of magnesium. This massive plane (230 ft wingspan, the longest of any military aircraft ever) had no fewer than 10 engines, 6 piston and 4 jets. The piston engines were of a pusher design, meaning they were at the back of the wing. This lead to several issues, as the carburator did not have proper heating, leading to carburator icing, which caused the engine to overheat and catch fire. While the B-36 had a solid saftey record for the time, crashes are inevitable, and the magnesium airframe burned very easily. It also was a nuclear bomber, and these problems did lead to a few broken arrow incidents. (Sry for the yapping, its just i like planes and magnesium is involved in the b-36 and the video) Sry

You can put out a magnesium fire. You need a special kind of dry chemical fire extinguisher designed for metal fires (class D), a lot of dry sand, or you need to replace the air with argon or an another inert gas (magnesium will burn in nitrogen too). Halon doesn't work BTW. Magnesium does not oxidize itself. But it will separate the oxygen from water and continue to burn, while producing flammable hydrogen gas. It's also an exothermic reaction (produces heat) that reacts faster as the temperature increases, causing a positive feedback loop and runaway reaction.

As a physicist and a chemist: No, the density of a material has nothing to do with any other characteristic (hardness, colour, how it will behave in a forge, etc). And even if you have just one material, you may have different "versions" of it, which may have widely different characteristics. Take Carbon for example: If you burn stuff like wood or coal, you get soot on your furnace. This soot is basically just carbon, really soft, black, basically no structural integrity. However, if you take this soot and put it into an environment with really high temperatures and incredible pressures, you get diamonds: The hardest material we know of and transparent. If we go back to metals: Remember tungsten? Really hard, heavy, incredibly high melting point. Now let's move a few steps to a theoretically similar metal: Quicksilver. Also really heavy, a liquid at room temperature and thus quite soft. (I have now information of how frozen quicksilver behaves). I could explain to you why it is like this, but not in form a youtube comment. And as a fellow blacksmith: Always think about the oxygen, when you work with hot metals: Of course you can tig weld, because you work with protection gas, which prohibits any oxide layer or fire. If you would have a method to both heat and work your metal in an protection gas atmosphere, you could use higher temperatures, which would make the metal softer and less likely to form cracks. But that is a lot of effort for next to no benefit.

A decent rule of thumb to determine if a metal is malleable is to look at the crystal structure. Hexagonal close packed (HCP) is typically brittle, face-centered cublic (FCC) is typically very malleable, and body-center cubic (BCC) is usually in between the other two structures. Magnesium is HCP hence the cracking and chipping when forging. Aluminum is FCC. Steel is BCC at room temoerature, but at forging temperatures, it transitions into FCC, giving it better malleability.

It seems like the cracking happened cause of the heat not being consistent through the whole piece. Since the core of the metal was starting out colder than the surrounding material you ended up getting internal stress in the metal. Induction heating would have given you a more even heat through the whole piece and a better chance to produce the shapes you wanted without cracking.

As a scientist: No, density is not directly related to hardness. An example would be lead, very dense but not hard at all. The hardness of a material is mainly related to the type of bonds that hold the material together (covalent bonds or ionic bonds, for example) and, in the case of metals, the material composition and the associated structure of the crystal lattice.

As a "Safety Lesson" they took a month's worth of magnesium shavings from all the lathes (he mentioned it was about a train car full) piled at one end of the parking lot and lit it up, burning 6 feet (almost 2 meters) through the asphalt, dirt, and stone. I'm sure they were very careful after that...

We stood back and just kept the fire from spreading. Wasn't any hope of us wasting time trying to put the shop out and saving anything with the supplies a backwood volunteer fire dept had (water). The dumb old coot found a dumber lawyer to try to sue us because we didn't try to spray water on it and save anything. Our lawyer had them both laughed out of the court room. Last I heard his insurance refused to cover anything because he never disclosed all the "dangrous" mag engine blocks he had stored together in a small space.

Every time he is working with magnesium (turning wheels, for example), he clears the working area, has cement floor + brick walls, and does so like it is the last thing he is doing at his shop. Also some salt, but he doesn't believe it is reasonable to use because you need to get close to put salt on it, and specialized salt fire extinguisher is quiet expensive. He got something like two or three magnesium fires, but because of preciouses and awareness it just kept burning in a lathe tray without damaging anything each time. And a long ventilation needed, because of the smoke.

Table salt for magnesium fires. The specialised fire-extinguishers (Class D if memory serves) for metal-fires (lithium, magnesium, titanium) usually sport either that or some other (really well dried) salt with no oxygen atoms in its molecule. The salt melts, coats the metal fire and strips it of contact with oxygen. Avoid baking soda (usual powder fire-extinguishers have that in them) or water, because the heat strips the oxygen clean off the molecule and you just fed live oxygen to the metal fire. And yes, table salt is hygroscopic so it will have some water from the moisture found in air so if you want, you could bake-dry some plain table salt and keep it in an airtight container for emergencies if you indend to machine spooky metals. Or just spend a couple of thousand pounds on a proper class-D fire extinguisher. And one more thing... AluMag powder (mix of alluminium and magnesium) was used in some unstable homemade thermite or explosive or something, I cannot quite remember, but shavings of those two together might be particularely hazardous.

We used magnesium engravings to make rubber printing plates. I took some old ones rolled up a piece 1" wide and a few inches long. Placed it in an old brass ashtray and lit it, once it was going good I hit it with the garden hose. It exploded impressively, throwing burning white chunks about. It burned right through the brass ashtray too. I am told old VW engine blocks could catch fire and the fire department would just let them burn because of that. I just watched a video and magnesium dust can be used to make a type of flash powder for fireworks.

Magnesium is very useful in pyrotechnics. A friend of mine gave me a piece of SU24 aircraft wheel rim. Which is made out of magnesium alloy . I used to file it down to get the fine powder and make flash powder or firecrackers out of it. I also did cut it out and melted it with Aluminium in 1:1 ratio to make very brittle Magnalium alloy,which is very easy to crush into finer powder and useful in pyrotechnics. But stuff is very dangerous to melt alone, it sparks and burns by itself,so that you have to melt aluminum first then add Magnesium into molten aluminium with constant stirring. To get the alloy, you have to pour molten alloy into bucket of water ro immediately cool down, otherwise all of the Magnesium will burn out leaving only Aluminium behind

@scarecrowforge Calcium is a grey-silver element. Bismuth is also a silvery grey, but when oxidized it displays a wide range of colors. However, those colors are from the oxide layers of varying thickness. The metal itself doesn’t have those colors. The oxide layers of titanium, iron, and others display that same property (thin film interference). Brass, and bronze are of course alloys that get their colors from the copper that makes up the majority of the mixture. So, there aren’t many elemental metals that aren’t silver, or grey. Just copper, gold, and cesium. Osmium does have a slight blue hue though.

@@hammerth1421 Sand also works great, but the reason they use salt commercially is that when the salt melts when it contacts the molten metal, it makes a crust around it and prevents oxygen from getting to it and re-igniting. Though, sand more than likely would work just fine for a smaller fire. There’s actually specific fire extinguishers for metal fires that are just pressurized tanks of super fine salt and/or soda that firefighters and certain labs use. They’re also like $6 grand if I remember right, which is kind of crazy if you think about it.

The extra fun part of magnesium fires in your workshop is that it burns hot enough to start an aluminium + iron oxide thermite reaction which is self oxidizing and burns at 2862c. Good thing there isn't a bunch of aluminium and iron dust around.

also, Copper - Has a reddish-orange color. Brass - An alloy of copper and zinc, with a yellowish-golden color. Bronze - An alloy primarily of copper and tin, with a brownish or reddish-brown color. Caesium - Appears as a pale gold color. Bismuth - Can have a rainbow-like iridescent oxide layer that gives it various colors, but pure bismuth itself has a silvery white color with a hint of pink. Rhodium - Often appears silvery but has a reflective, mirror-like finish which can sometimes give off a bluish hue. Osmium - While generally grey, it has a bluish tint.

Not sure if anyone has mentioned this but the likely reason behind the magnesium appearing harder to file is that because it is less dense, it’ll actually clog up the teeth on the file at a faster rate. So similar to how putting aluminium on a grindstone would clog up the abrasive surface 😊 (before anyone says anything, no I would not use a grindstone with aluminium)

At sea level, 0 C water freezes and 100 C water boils. 20 to 25 C is nice temp, 30C sucks. It's pretty easy. Freedomheit is all over the place, 33 F, 212 F, 68 to 77 F and 86 F respectively. You should put the kiln next to the power hammer so you don't run around with hot metal in the shop.

If memory serves, Fahrenheit was designed using the thermal properties of brine (don't recall the concentration). Thus it correlates decently to human temps in whole numbers (since humans are mostly saltwater). However, beyond that bit, it doesn't scale terribly well, which if you're doing science, you very much want. Celsius was designed around pure water, so the 'human ranges' are smaller, but its very scalable, making it more useful for most other applications. Fun fact: due to technical limitations, 100F used to be the standard internal human body temp. Once thermometers got better, we realized that its closer to 98.6F; however it seems to possibly be dropping slightly in the modern age.

The easiest answer to the correlation between density and hardness is that gold and lead exist. The longer answer is that there is some relation between density, stiffness (Young's modulus), and even melting point to some extent. If you multiply the density in g/cm^3 by 26.7 you roughly get Young's modulus in GPa... for magnesium, aluminum, titanium, manganese, and iron. Most other metals will be way lower. Beryllium and chromium are actually way above.

@@bjornthorgudmundsson2781 the thing is they are both hardened steel but old saw were hardened completely and heated again to be sharpenable. New saws are impulse hardened which means if I'm not mistaken that they use a high voltage on the teeth to heat it up and harden but the rest of the saw is not hardened at all. So the teeth are just as hard as a file but the back should be much softer.

Looked it up and it's based on An 50/50 ice Salt mixture what the heII does that have to do with humans or anything?

2:10 I'm not 100% sure but i don't think density and hardness are very strongly correlated. Gold and Tungsten have very similar density, but very different hardnesses. I suspect it's got more to do with melting point, since iirc germanium can be chewed like bubble gum due to its low melting point and i supposed mercury is a liquid so would be "soft"
