Type III – Hardcoat

Overview

The Type III Hardcoat Anodize process produces superior hardness and denseness. When a part is hardcoated, it increases the micro finish 2-5 times, depending on the alloy.

Some industrial applications of Hardcoat Anodizing include highly intricate parts such as pistons, anti-lock brake assemblies, pump components, valves, sliding parts, insulation plates and transmission parts. Some retail applications for Hardcoat Anodizing and Sulfuric anodizing include cookware, bike rims, locks and levels.

Key Performance Properties Type III Hard Coat Offers:

• Unmatched wear properties
• Coatings wear as well as or better than hardened steels
  (HRC values of 70) as judged by Suga and Taber wear tests
• Can achieve salt spray resistance in excess of 1000 hours
• Can achieve very tight tolerances
• High dielectric strength to 2000VDC
• Heat dissipation
