Tungsten Carbide Die

Tungsten Carbide Die


Commonly used tungsten carbide die include cold heading dies, cold punching dies, wire drawing dies, hexagonal dies, spiral dies, etc., which are widely used in the die industry.

Advantages of cemented carbide molds:
1. Cemented carbide has high hardness, high wear resistance and high red hardness, and can maintain ≥56HRC hardness at high temperature of 550℃;
2. Has a high elastic modulus, generally (4~7)×104kg/mm2, and has good rigidity at room temperature;
3. Has high compressive strength greater than 6000MPa;
4. It has good oxidation resistance and corrosion resistance, and is not easy to be oxidized under acid and alkali resistance and high temperature;
5. It has a low thermal expansion coefficient and is suitable for manufacturing high, precise and sharp precision molds.

Cemented carbide dies can be divided into five categories according to their uses:
1. Carbide top hammer
2. Carbide wire drawing dies (this type of dies accounts for the vast majority of tungsten carbide dies)
3. Dies for cold heading, cold punching, forming and shaping
4. No magnetic mode
5. Hot work carbide die
