                | 1. Spherical WC.W2C eutectic particles prepared 
                  by atomization at ultra-high temperature or other spheroidizing 
                  method 
 2. Specification: ranged from 20 microns to 250 microns, powder 
                  of single or mixed particle size are available
 
 3. The particles are regularly spherical. The microstructure 
                  is homogeneous, dense and dendritic structure
 
 4. The powders are mainly used for petroleum Oil Drilling Tips,PCD 
                  drilling tools,melting and penetrating,spray coating and built-up 
                  welding on wear surface
