You also need both iron oxide and aluminum powder to make thermite. It’s amazing what metal can achieve when it works together.

Aluminum “rusts” as well. White rust. Aluminum oxide.

And if you combine that with magnesium powder, you can make a historic doping agent to coat your zeppelin with!

It doesn’t matter. This story, like all the others on 4chan, are fiction.

Yeah but like, in order to get significant amounts of it you gotta be in a relatively harsh environment.
Olhonestjim@lemmy.world 1 month ago
You get a lot of it at sea. Not supposed to polish it off though, because the aluminum oxide acts as a barrier to further corrosion, whereas iron oxide flakes and continually exposes fresh surface.

Yeah I imagine you would. Salty water loves to eat things up.

Under a car and in contact with iron is enough. I love my aluminum body cars but man, you need to be careful selecting fasteners.
Liz@midwest.social 1 month ago
Yeah that’s true, metal to metal contacts can have some fun interactions.

Dunno how harsh a warehouse is. We used to get oxidized stuff for our presses a lot
Liz@midwest.social 1 month ago
It depends on what’s in the warehouse. The only place I’ve seen significant aluminum corrosion was inside a vac frame hood with years of corrosive fumes in it. But, I’m sure there’s a middle ground. Aluminum isn’t inert, but it’s better than raw iron at resisting corrosion.
Sam_Bass@lemmy.world 1 month ago
Really depends on the grade of material. Aluminum has several different grades of varying hardness, ductility, resistance. Same as steel. Corrosion is the bane of most usable metals and industries are constantly researching methods to fight it

in fact, it rusts so fast, that it’s pretty much impossible to get a “clean” aluminium surface while oxygen is around

Then it just rusts again

Yeah. Shame we cant live in a vacuum

They had to invent an entirely new style of welding to weld it correctly because it rusts so much you can’t even melt it for welding reliably.
