About cemented cardide

About cemented cardide・・・It is mainly used as a tool material

Co (cobalt) (as adhesive is added to particles of WC (a mixture of tungsten and copper powder), mixed, and heated at 1500°C.

Our cemented carbide is a high grade cemented carbide with uniform structure of grains based on accumulation of technology and strict quality control for many years.
