COATING TECHNOLOGY
CRN Coating
Specially designed for milling copper electrodes and copper alloys.
CRN coating has been developed for copper alloy milling. It has superior wear resistance and excellent adhesion strength by using Miracle coating technology. The excellent anti adhesion properties needed for copper machining has been achieved due to its low coefficient of friction at high temperatures.
