Cast Tungsten Carbide powder, -80 to + 230 mesh, – 230 mesh, – 200 to +230 mesh
Formula
WC/W2C
Composition
4.0±0.2 wt%carbon and 96 ± 0.2 wt%tungsten
Manufacturing Method
“By melting tungsten metal (W) 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. The solids are crushed and classified to various mesh sizes.” (quoted from ITIA web)
