It rusts just like iron, but the rust (AlOx, or alumina) stays bonded to the metal and actually protects it.

- lloeki 5mo agoRust being literal Fe2O3 makes a convincing argument that aluminium sure oxidises but doesn't rust pretty much by definition ;)
- wongarsu 5mo agoIn other words: it rusts, but it doesn't rust like iron. It rusts in a much less destructive way because the aluminum oxide protects the rest of the aluminum from oxygen
- redeeman 5mo agoit does not rust, it corrodes :)
