By adding Al to TiN a coating is created with improved abrasion resistance and heat resistance. When operating temperature exceeds 700℃, the Al component and oxygen are combined by frictional heat, and strong Al2O3 is generated on the outermost layer, contributing to further improvement of the lifetime.

Oxidation resistance/ Heat resistance improving carbide
Cutting tools/ Cold heading tool
Punching dies/ SUS machining die (mold for processing)
