 Cast Tungsten Carbide Powder     

 
 

  M.C.T. produces cast tungsten carbide powder from 5 mesh (4000micro)down through 800mesh(15micro)。The products have high content of fine feather-like or acicular grains with maximun up to 92% and good wear resistance,mainly used in applications requiring wear-resistant coatings(hardfacting),such as hardfacting of oil drilling tool,as well as easily-wear components of engineering machine.
