Anodizing Process: Floturn Inc.

ANODIZING PROCESS. Aluminum anodizing is the electrochemical process that produces a stable film of aluminum oxide on the surface of the aluminum part at room temperature. The oxidation that occurs during the anodizing process creates an extremely hard and abrasionresistant surface, increasing durability and corrosion resistance.
