Cemented carbide stamping abrasives are mainly used to process workpieces such as bolts and nuts in industrial production. The advantages of stamping processing are high utilization rate of materials, low metal consumption, high production efficiency and high degree of automation. The mold has to bear huge impact force during the working process, so the mold material is required to have high hardness, high wear resistance, high impact fatigue strength and sufficient impact toughness.

Carbide stamping abrasives have good performance and have the following characteristics:

1. High strength and high hardness, still has high hardness at higher temperature

2. High elastic modulus, good rigidity, no obvious plastic deformation under stress

3. High compressive strength, can withstand large loads and keep the shape unchanged

4. Good wear resistance

5. Small thermal expansion coefficient

6. Good chemical stability
