Hard Anodize

Hard Anodize (Type 3)

Hardcoat anodize, often called Type III Hard Anodize, is an electrochemical process used for aluminum components subject to extreme wear or corrosive environments. Thicker and denser than Type II, hard anodize is often specified for applications requiring superior abrasion resistance, a thicker coating, or enhanced electrical insulation. Since the thickness can be built up, hardcoat is valuable for salvaging worn or over-machined parts.
