WC-TiC duplex carbide solid solution maintaine high hardness,high wear resistance etc., excellent performance of titaniumcarbide, is basic mateiral of series of WC-TiC-Co cemented alloy,are widely used for continuous cutting thoughness material. Theycan significantly improve the red heat, anti-oxidation, corrosionresistance and other properties of the alloy. Are more suitable forthe processing of steel than WC-Co cemented carbide alloy.
