Type III aluminum anodizing, also called hard coat anodizing or hard anodizing, is used to increase the wear and corrosion resistance, increase the surface hardness, and improve the thermal and dialectical properties of treated aluminum objects. The ability to retain lubricants, PTFE coatings (like Sanford Hardlube™), also improves with Type III anodizing.

Chromate, Iridite, and Alodine Conversion coatings passivate the aluminum surface and protect the article from corrosion while retaining conductivity. These coatings can be used as adhesion promoters. The processes are sometimes referred to as chemical film.
