Detailed Description
■ 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.
