Spherical Cast Tungsten Carbide (YZDF)
 
■ Spherical WC.W2C eutectic particles prepared by atomization at ultra-high temperature or other spheroid zing method
■ Specification: ranged from 20 microns to 250 microns, powder of single or mixed particle size are available
■ The particles are regularly spherical. The microstructure is homogeneous, dense and dendrite structure
■ The powders are mainly used for petroleum drilling bits, PCD drilling tools, melting and penetrating, spray coating and built-up welding on wear surface
