COATING TECHNOLOGY

CRN Coating

Specially designed for milling of copper electrode and copper alloy.

CRN coating has been developed for copper alloy milling. It has superior wear resistance and excellent adhesion strength by applying Miracle coating technology. And also, it exhibits excellent anti adhesion properties against copper due to its low friction coefficient at high temperatures. FEATURES OF CRN COATING   CRN (Al,Ti)N Carbide Hardness (HV) 2,000 2,800 1,600 Adhesion (N) 80 80 -	Friction Coefficient against copper at the high temperature of 600°C
