Because of the high hardness, wear resistance and corrosion resistance, the tungsten carbide slitting knifes which made by powder metallurgic method are widely used for the cutting of non-ferrous metal, paper, chemical fiber, graphite and plastic.

The components of tungsten carbide are WC(hard phase) and cobalt (binder phase). The physical properties of alloy depend on the grain size of WC and the percentage of hard phase and binder phase, we have dozens of material grades for your different applications.
