Aluminum components can be anodized by using Oxidite processes. This additional treatment increases the corrosion protection, wear resistance and improves appearance. Furthermore, the anodized surfaces for decorative reasons can be colored during the anodizing process or painted afterwards.
Chromium-free conversion coatings such as Iridite NCP, provide corrosion protection equal to chromate finishes on most aluminum alloys. The coating can be used as a final finish and can also serve as a base for high performance topcoats, powder paints, lacquers, or as a base for rubber bonding and is completely free of chromium and does not contain cobalt.
