Does Aluminum Rust? Rusting is a form of corrosion that's specific to iron and steel (because it contains iron). In fact, rust is the common name for iron oxide, when iron or steel bonds with oxygen and undergoes oxidation. Therefore, aluminum can't rust.

Does coated aluminum rust?

Aluminum by its nature does not rust. ... It will not have red/brown rust colors like untreated steel can have; instead it will oxidize into a cloudy and white powdery finish over a long period of time in adverse conditions.

How do you keep aluminum from corroding?

Painting, anodizing or any surface treatment that forms a coating on the aluminium surface will protect the surface from pitting attack. In applications when you want to preserve the aluminium look and still have a surface resistant to pitting, a clear coat or thin anodic coating would be suitable surface treatments.
