1 and WC (tungsten carbide) are very hard, wear-resistant and high-temperature resistant alloy carbides, which generally exist in tungsten-containing steel in the form of alloy carbides, and there are also pure WC made by powder metallurgy.

2. Tungsten carbide is a compound composed of tungsten and carbon. Its molecular formula is WC and its molecular weight is 195.85. It is a black hexagonal crystal with metallic luster and hardness similar to that of diamond. It is a good conductor of electricity and heat.
