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.
We will offer you by processing, sintering to your desired shape.
Carbide material plate
With express delivery such as fast delivery items and developed goods Utilizing top and bottom grinding carbide plates and We are stocking black skinned carbide standard plate.
