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

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

        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.

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

      Yeah but like, in order to get significant amounts of it you gotta be in a relatively harsh environment.

        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.

        Dunno how harsh a warehouse is. We used to get oxidized stuff for our presses a lot

          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.

            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

          Yeah that’s true, metal to metal contacts can have some fun interactions.
