Cemented carbide is a kind of alloy material made of refractory metal hard compound and bonded metal through powder metallurgy process. Cemented Carbide has a high hardness, wear resistance, strength and toughness, heat, corrosion and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature also basically remain unchanged, at 1000 ℃ still have a high hardness.
