Description
Metallic aluminum naturally forms a thin, transparent oxide layer that provides corrosion protection. Anodizing is an electrochemical process that quickly builds-up this oxide layer. Anodized aluminum is usually silver, gray, or brown, but the layer readily absorbs dyes of any color. The electrochemical process for anodizing was first developed in the 1920s and was initially used for electrical applications. After World War II, anodized coatings became popular for architectural construction because of their corrosion resistance and decorative colors.
