◆ Alloyed powder
Fully carbonized and dense alloyed powder．
Carefully chosen material，special process to guarantee the preferable growth of grains．
Compared With the conventional tungsten carbide，YJ has more uniform structure，better thermal stability and
coarser WC grains．
Particle Size 20 micron ranged from from microns to 40mesh(American standard)．
