Does aluminum rust

Yes, Aluminum does rust, but when aluminum does rust, it doesn’t rust like iron does until it’s gone. The oxidation of metal by oxygen in the air is rust. Aluminum reacts chemically with oxygen to form aluminum oxide, which is aluminum rust. Aluminum rust is very thin, its thickness is only ten thousandths of a millimeter, but it is very hard and very wear-resistant. It clings to the surface of the aluminum so that the aluminum inside is not exposed to the outside air, preventing the aluminum from continuing to rust.
