The Hard Coat Anodizing Process

Hardcoat Anodizing

Hard Coat Anodizing

Hard coat or hard anodizing (Type III) is similar to standard anodizing, (Type II) in as much as 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.

Hard coat anodized films can also be grown to greater thickness, typically .002 inches or more.

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 and some darker shades of color.
