YJ Alloyed Powder (Single-crystal WC 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 uniforms structure, better thermal stability and coarser WC grains;
■ Particle size: ranged from 20 microns to 5mm(American standard);
■ Single crystal WC Powder is widely used as hard-surfacing material in diamond built-up welding on matrix and PCD drill pipe coating. It is a new kind of cemented carbide material.
