Macrocrystalline Tungsten Carbide (MWC) Powders
Monocrystal large-grain tungsten carbide is featured with high hardness and excellent wear resistance, with its hardness ranks only second to diamond. It is mainly used to improve the abrasion resistance of engine blades, driving gears and other components like driving parts and shafts in the aerospace industry, as well as in rocket, thermal spraying, atomic energy and high-tech fields like metallurgical automation, aerospace and cemented carbide.
