Anodizing is an electrochemical process producing a nonconductive, durable, industrial coating with excellent corrosion resistance which can be provided in a variety of colors.  The surface of aluminum has a thin, natural occurring oxide coating. The electrochemical process of anodizing increases the thickness of this coating in order to resist abrasion and corrosion; the thicker the coating the greater the resistance.

Hardcoat or hard anodizing (Type III) is similar to standard anodizing (Type II) in that it also creates a film of aluminum oxide on the part.  It is produced at colder temperatures and provides a surface that is harder, smoother, and more wear and corrosion resistant than standard anodizing. 

Hardcoat finishes are typically darker in appearance than standard anodizing depending on the coating, thickness and alloy.  A variety of colors are available on thinner coatings.  Heavier coatings can be dyed black or some darker shades of color.
