Cast Tungsten Carbide Powder

By melting tungsten metal and tungsten monocarbide (WC) together, a eutectic composition of WC and W2C is formed. This melt is cast and rapidly quenched to form extremely hard solid particles having a fine crystal structure. A tough, feather-like structure is preferred over the brittle, blocky structure obtained by insufficient quenching. The solids are crushed and classified to various mesh sizes. Cast carbide is used for hardfacing many alloy blends, drills, laser cladding, and other hardfacing applications. Cast carbide has been widely used in petroleum and construction machinery.
