Corrosion-Resistant Aluminum

Aluminum is a very active metal, meaning that its nature is to oxidize very quickly. While a weakness for most metals, this quality is actually the key to aluminum’s ability to resist corrosion. When oxygen is present (in the air, soil or water), aluminum instantly reacts to form aluminum oxide. This aluminum oxide layer is chemically bound to the surface, and it seals the core aluminum from any further reaction. This is quite different from oxidation (corrosion) in steel or iron, where rust puffs up and flakes off, constantly exposing new metal to corrosion. Aluminum’s oxide film is tenacious, hard and instantly self-renewing.
