Specialty Hard Coat Anodizing and Teflon Seal
Benefit
Type III Hard anodizing is used when an increased wear and abrasion-resistant coating is needed. The aluminum oxide coating is thicker than regular anodizing, which gives the metal surface additional protection. Parts can be processed at lower temperatures, but increased electrical flow is required.
