Nicholas, Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.

Anodizing uses acid to create a corrosion- and wear-resistant layer on top of a metal. The process of anodizing also changes the crystal structure near the surface of substances, like aluminum alloy, which allows you to dye the metal a bright color.
