Hardcoat Anodizing

Hardcoat Anodizing, type III anodizing, is a more robust form of anodizing aluminum, providing a harder, more resilient finish. While Standard anodizing provides some protection to the surface, and vibrant color options, Hardcoat anodizing is many times more resistant to the effects of impact and abrasion. Similar to standard anodizing, or Type II, Hardcoat Anodizing involves submerging the part in a sulfuric acid solution for a specific amount of time to provide a coating on the surface of the aluminum. In Hardcoat Anodizing, Clear(which results in a grey color) or Black Dye can be applied to alter the appearance of the solution. Colors are not available in this process.
