Can aluminum coil rust?

Aluminum coil does not rust in the traditional sense. Instead, it forms a thin, protective layer of aluminum oxide when exposed to air, which prevents further corrosion. This oxide layer is different from rust, which is iron oxide. While aluminum can tarnish or corrode under certain conditions, such as exposure to certain chemicals or in extreme environments, it does not rust like iron or steel. Proper storage and handling can help maintain the integrity of aluminum coils and prevent unwanted reactions.
