[0002] Tungsten carbide round rod is also called tungsten steel round rod. Tungsten carbide is a composite material composed of refractory metal compounds (hard phase) and bonding metals (bonding phase) produced by powder metallurgy. Cemented carbide (WC) is an inorganic compound containing equal amounts of tungsten and carbon atoms.
