Field’s Metal vs Aluminium

Field’s Metal vs Aluminium

[“Cartoon Space Utopia” intro music] All right everyone welcome back to Cody’sLab. So, I have here a chunk of aluminum. See, angle ‘luminum It’s about three nano light seconds long But of course, I’m only gonna be using a small piece of it because today I want to actually destroy it using a liquid metal. You might have seen mercury destroying ‘luminum or gallium destroying ‘luminum What I’ve not seen is an alloy, which is liquid at a higher temperature also doing it and I think it should as long as the metal can dissolve the ‘luminum then it should catalytically destroy it as mercury will So I’m gonna try this out with some field metal. This is an alloyed mixture of 32.5 and a half percent bismuth 16.5 and a half percent tin and 51% indium Okay, so that should be our alloy constituents and I gotta find a spoon or something to melt it down in It of course takes a much higher temperature to melt it down right now because all the metals are separate and they don’t actually lower each other’s melting point until they’re actually mixed. But as soon as they do start mixing you see they know quite quickly Come on. There it is. We have a liquid What I like about this alloy is it’s all non-toxic materials You know bismuth indium and tin none of those are very toxic There’s a pretty bit of metal See sticks to things. In fact, this could be used to make a mirror I think That’s what that burn was there, -chuckles- well that’s cooling let’s cut off a piece of this ‘luminum I really need to bolt down my vise -laughs- There is one problem with this metal Takes forever to solidify So I’ve got some water here that I’ve warmed to about 80 degrees centigrade So now let’s drop in the metal and see if it melts, it should It’s meltin’ Good as you can see we’ve moved over to the hot plate and Right now I’m just kind of scratching the aluminum to get rid of that oxide coating If you’ve ever tried to react ‘luminum with another metal, you’ll know that it’s not exactly trivial ‘luminum forms an oxide coating which is rather difficult to get through That, uh, that should help but of course the coating forms almost immediately Oops, I just rolled right off there. Maybe I should drill a divot into it Okay, it’s very similar to working with mercury just a little higher temperature Notice I’m scratching at it Underneath of the metal so the oxygen can’t get to it Okay See, there’s a little bit of oxide forming already. I’m not sure if that’s from the tin and indium or if it’s from the ‘luminum This is what it currently looks like So this is just after putting the bit of metal on there and then stirring it around So it made good contact with the ‘luminum And now I’m gonna check on it maybe every half an hour or so Okay, 4:00 a.m And look at this Looks more or less the same except there is a little bit of like a gray around it. So it is affecting the ‘luminum At 4:30 I can’t really tell… I think that dark spot is increased in size Okay it has definitely altered the– piece of ‘luminum. Let’s see what happens if I– tried bending it See if it’s made it brittle yet Okay, the metal appears to be still quite strong. Let’s tip it over a little bit Let’s see what it’s done to the actual metal. Doesn’t appear to have eaten a creator into it or anything Okay, so a bit of time has elapsed You can see the ‘luminum has changed substantially though now this was weird because Most of this change happened after I turned to the hot plate off you see at about 8 a.m I had to leave and I didn’t want to leave the hot plate running so I just turned it off let everything cool and when I came back I came back to this so the metal has– obviously oxidized– substantially, so the– fields metal is soaked through the ‘luminum and– disrupted the oxide coating in this area and then the air was able to attack it so if you flip it over and see it hasn’t gone through all the way but it has gone to the edges here There’s a couple of spots So it seems to soak through laterally more than vertically. Yeah, the the ‘luminum is still quite strong That makes sense because it hasn’t destroyed or interacted with the majority of it But this is proof that the fields metal will attack ‘luminum So let’s turn the hot plate back on Let’s let it sit on here for a few more hours with the metal liquid and see if it soaks through even more Okay, just after 5:30 so you can see that there is a little bit of a gray a different colored silvery gray outline around this dark Grey mark, the ‘luminum isn’t being oxidized substantially It’s not until I cool it off that it starts to really destroy it So maybe doing a thermal cycle would be more effective So let’s actually turn the hot plate off Let’s let it cool down again and see if that works See we kind of mark it or the outline of that Area is and then where this currently is But if anyone has any idea why it causes the ‘luminum to really fall apart When when it’s cooling off, please let me know And here we are it is… just after 7:00 And it has indeed… marched along with the– destruction of the ‘luminum I’m looking over this edge here. That’s kind of interesting Let me zoom in on that. Yeah, look at that. It’s like it’s crawled off the edge there. That’s pretty cool. And of course It is now hard So, yeah, it does seem like it’s thermocycling it really does have an effect Look around on the backside here Looks like these areas are a little bit larger than last time a little bit on this corner here That makes me think that maybe we finally weakened it Yeah, certainly not like that well, let’s heat it up and lift the metal melt again, let’s give it another cycle It’s almost eight Here’s the metal it’s all warmed back up Let’s see if I can break it in half It’s still a little bit hard to crack but look at that I just pulled it right apart! I probably couldn’t have done it just with my fingers– especially since it’s so hot, but that was definitely substantially weaker. I like how it like… had a juicy center almost So this gray scale on the ‘luminum is not superficial like it goes pretty deep into it the metal just completely crumbles. So one last quick little experiment here. Let’s put some of this into some warm water Ahh, It’s reacting Okay, so it’s the extra sensitive to moisture Might explain some things It’s actually decomposing the ‘luminum and ‘luminum oxide and hydrogen gas Let’s put some soap in the water so we can capture those bubbles. Let’s see if they can be ignited Let’s throw this other piece in there too Yeah, we got it going Turn off the lights now Let’s hit this with the torch and see if we get it some hydrogen burning Huh That’s a way to get hydrogen out of water shields metal plus ‘luminum So, I hope you all enjoyed and I’ll see you next time [“Cartoon Space Utopia” outro music]

  1. it might be that its unable to mix with the aluminium at sertern temps you could try diferend temps to increase the reaction

  2. Keeping it heated is now allowing moisture build up through the field's metal.

    Only when you let it cool down is water in the air able to condensate inside the aluminum and allow a chemical reaction to occur, thus destroying the aluminum.

  3. I has a question, it may be dumb, but… How are you able to hold the glass tube and melt the metals together without burning your finger tips off? Surely the entire piece would be extremely hot unless my lack of a properly education in chemistry is why i assume that glass is like any old piece of glass?

  4. the fields metal has a set temperature that it reacts with the aluminum. when you heat it, it passes that temperature to quickly on cooldown it passes it more slowly and has a chance to react. figure out what the temperature is and you can heat it just to that point and keep it there and destroy the aluminum a lot faster.

  5. That's pretty neat! I wasn't expecting that reaction at the end. I was kind of hoping you would have taken the two pieces you broke and let themselves weld back together to see what happened with another cycle or two.

  6. Imagine how much fun you would have if lead, mercury, and cadmium weren’t toxic. Lead sculpture would be taught in middle school art class, kids would have a blast playing with lead foil while eating leaded jolly ranchers, which I bet would be delicious. Literally everything would be made of lead!!! Cadmium would make cheap jewelry last forever and don’t even get me started on liquid metal! Uggggghhh I WISH THEY WERE SAFE

  7. I wonder if the extrusion aligning the crystals has anything to do with a lateral spread, like, it works down the grain boundaries that are aligned lengthwise

  8. @Cody'slab i have aluminium rims on my Tomos moped. I have slime brand tube sealant in the tubes. My coworker claimed that the slime will eat through the aluminium. Can you prove or disprove this?

  9. I used to mix gallium and aluminum all the time, if I recall the left over material when mixed with water gives you hydrogen.

  10. i was looking for the video where you combined aluminum and gallium then reacted that with h2o to make hydrogen. is there any process of splitting the aluminum and oxygen from the al2o3 to form it back into aluminum, potentially make an engine that is a closed loop requiring only water and some other inexpensive chemical/s. Even if it was a vapor process it would fascinate me to hypothesize a self repairing engine that plates itself to counter natural wear?

  11. Why did you use grams and celcius we dont understand this unit
