question about aluminum

Aluminum oxidizes, which is a protective layer actually. You can polish, sand it etc. and the oxide will immediately re-form.

So you can sort-of call oxidation "aluminum's rust" but it's only billionths of an inch thick, and will not corrode like iron will. It does corrode, but in a normal environment this will take decades or even centuries...

I sit corrected!

All metal (aside from gold and a few others) corrode, and oxidize.. aluminum oxide is easy to beat- some metal polish and a little elbow grease
