Cast tungsten carbidepowder: Particle Size should be in line with: Powder weight percentage for upper size should be no more than 5%,; for lower size no more than 7%, and the particle size for cast tungsten carbide can be produced according to customers' requirements.

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.

1. US-standard mesh:-8~+400
2. hardness? (HRA):93
3. grey color with?luster
