Introduction Cemented Carbide (W108 Commerial)
Cemented carbide is made of refractory metal hard compound and binding metal through powder metallurgy technology made of an alloy material.
Cemented carbide with high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even under the temperature of 500 ℃ is basic remains the same, there are still very high hardness at 1000 ℃.
