Introduction
Carbide stamping dies represent the pinnacle of modern manufacturing technology, combining superior material properties with precision engineering to deliver unparalleled performance in metal forming operations. This comprehensive guide explores the material characteristics, advantages, and applications of carbide stamping dies in industrial manufacturing.
Material Properties of Carbide Stamping Dies
Chemical Composition
Carbide stamping dies are primarily composed of tungsten carbide particles bonded together with cobalt. The typical composition includes:
- Tungsten carbide (WC): 85-95%
- Cobalt (Co): 5-15%
- Other carbides: Small percentages of titanium, tantalum, or niobium carbides
Physical Properties
- Density: 14.5-15.2 g/cm³
- Hardness: 68-73 HRC (Rockwell C scale)
- Compressive strength: 2,000-7,000 MPa
- Young's modulus: 500-650 GPa
