DESCRIPTION

MIL-A-8625 Type III Class 1 (Non-Dyed) and Class 2 (Dyed Black) 

Aluminum Hard Coat Anodizing is similar to standard anodizing in that both are controlled electrochemical processes. The key difference is that hard coat anodizing provides a surface that is more wear resistant and has a smoother and harder surface than standard anodizing.

Modified hard coat anodizing which sometimes called hard coating or hard anodizing is an electrochemical process that provides corrosion protection to aluminum and aluminum alloy parts or pieces

Hard Coat Anodized Aluminum is used for the following reasons:

Corrosion resistance

Increase hardness
Electrical Resistance
Lightweight properties
Flame resistance
Temperature Resistance
