Galvanization occurs when two different types of metals are positioned in a way that forms an electrical circuit. The most common type of aluminum corrosion is galvanic corrosion, which occurs when aluminum comes in contact with other metals. While the protective aluminum oxide layer is very resistant and can renew itself after sustaining damage, certain factors may cause it to become unstable. Does Aluminum Corrode? Yes.Īlthough aluminum has an edge over many other metals, it’s not immune to corrosion. The difference, however, is that while rust flakes away, exposing more raw metal to corrosive elements, aluminum oxide seals aluminum’s surface preventing anything else from reacting with it. When exposed to oxygen in the air, water, or soil, aluminum reacts to form a thin coating of aluminum oxide that chemically bonds to its surface.Īluminum oxide hardens onto the metal as a greyish-white powdery substance, similar to how rust develops on metals like steel. However, the metal’s reactivity comes in handy in protecting itself from the elements. Technically, pure aluminum would dissolve when exposed to water. Can Aluminum Rust? No.įirst off, it’s important to understand that aluminum is a highly reactive metal, especially in its pure form. Learn more about the different forms of corrosion aluminum is susceptible to and its corrosion resistant properties. However, aluminum corrosion is often more subtle. Rust causes metal to change in color and consistency, making it easy to spot.
