Alloys are anodized to increase corrosion resistance, to increase surface hardness, and to allow dying (coloring), improved lubrication or improved adhesion. Most aluminum aircraft parts, architectural materials, and consumer products are anodized.

Anodized aluminum can be found on mp3 players, flashlights, cookware, cameras, sporting goods, window frames, in electrolytic capacitors and on many other products because of its’ corrosion resistance and its’ ability to retain dye. Although anodizing only has moderate wear resistance, the deeper pores can better retain a lubricating film than would a smooth surface.
