Can aluminum coils rust?

Aluminum coils do not rust in the traditional sense. Aluminum reacts with oxygen in the air to form a thin, protective layer of aluminum oxide on its surface, 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 harsh environments, it does not rust like iron or steel. Proper storage and handling can help maintain the integrity of aluminum coils and prevent any form of corrosion.
