Anodized Aluminum

ASTM B209

Anodized Aluminum is stronger and more durable than mill finish aluminum. The process of anodizing allows for the steel to embody these characteristics. Anodizing involves an aluminum coil or sheet being placed into a chemical acid bath. An electrical current is passed through the acid, causing the surface to oxidize. The oxidation forms a strong coating on the surface of the aluminum.

Anodize aluminum is commonly found in applications where the material may be exposed to the elements. It is also found in kitchen equipment like pots and pans because the material distributes heat evenly.
