Customised Cemented Carbide Components Producer And Exporter
Description: At present, the majority of tungsten carbide stamping dies using WC-Co alloy . This tungsten carbide has high hardness, high melting point, stable, suitable for making the mold material. Because lubricity of WC is better than Co, and with high solubility at high temperatures; at normal temperature, WC solubility ratio of Co is small, so it can maintain a certain toughness. WC-Co cemented carbide is currently the most widely used, the largest output of carbide.Thanks to the combination of WC and Co properties,they have excellent performance
Tungsten carbide stamping dies mainly processing of bolts, nuts, steel wall
nails, wood screws and rivets and other common parts in industrial
production.Conventional bolt cold forming process can be divided into expected,
upsetting head, accumulate, forming, gaining five steps. Stamping advantage are
the high material utilization, metal consumption, high production efficiency,
high degree of automation. In the course of the stamping dies
working ,it had to bear a huge impact, unit pressure up 200MPa, and therefore
requires a mold material with high hardness, high wear resistance, high impact
strength and fatigue sufficient toughness.
Features:
1. Adopting 99.95% high purity raw material tungsten carbide powder and cobalt.
2. The hardness of the cold heading die reaches HRA88 or above, and the bending strength reaches 2400 or over.
3. It has high impact resistance and impact resistance.
Tungsten carbide Stamping dies material has the following characteristics
1. High wear resistance. Tungsten carbide stamping dies material high wear resistance, tensile modulus can be guaranteed long-term work in any degree of deformation, ensuring standard size unchanged.
2. Excellent in polishing. Carbide has a good polishing, can be processed into
the die hole mirror light, ensuring high quality standard surface.
3. Adhesion to metal is small. In the tungsten carbide stamping process,
ferrous metal material adhesion small carbide tooling materials, ensuring a
high tungsten carbide stamping die life.
4. The friction coefficient and energy consumption is small.
5. High thermal conductivity. Since the thermal conductivity of the tungsten
carbide die is high, heat generated during the stamping can quickly conducted
away to improve the durability of the mold.
6. Good corrosion resistance.
