      Because of the high hardness, wear resistance and corrosin resistance, the tungsten carbide cutting and slitting knives what made by power metallurgic method are widely used for the cutting of nonferrous metal ,paper chemical fiber graphite and plastic

      The components of tungsten carbide are WC (hard phaes) 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.
