Type III aluminum anodizing services enhance many desirable properties of aluminum. It improves electrical resistance, thermal conductivity, and provides the part with the hardness of steel.

The build up for hardcoat anodizing services is much thicker than your standard anodizing. The typical build up of this coating is 0.001î and also 0.001î penetration into the material.

The color of the aluminum oxide build up from hard coat anodizing depends greatly on the alloy of the aluminum material. The color can range from a champagne/gold hue to a dark gray.
