Cast Tungsten Carbide Powder

Cast Tungsten Carbide (CTC) Powder is made of melting and crushing W and WC and is irregular dark gray particles with a high melting point (2525℃), high hardness (≥ 2000 HV0.1), and excellent wear resistance.

CTC is used to prepare PDC matrix bits powder, Plasma Arc Welding (PTAW) powder, spray welding materials, cemented carbide wear-resistant electrodes (wire), etc. The primary purpose is to pre-reinforce wear-resistant surfaces or repair worn surfaces for mining, oil & gas, metallurgy, construction machinery, agricultural machinery, and steel industries.
