Product Description

Product Description
Or called casting tungsten carbide, tungsten casting carbide ,which is made by melting tungsten metal (W) and tungsten mono-carbide (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. The solids are crushed and classified to various mesh sizes required.
