Precision YG15 Tungsten Carbide Punch Professional Manufacturing Solution


YG15 tungsten carbide punches utilize premium hard alloy material with 15% cobalt content, offering exceptional hardness (HRA87) and outstanding impact resistance. Our precision manufacturing process ensures dimensional accuracy within ±0.002mm and achieves mirror-like surface finish of Ra0.1, meeting the most demanding industrial applications.

Precision Manufacturing Process

1. Material Preparation Stage

  • Uses high-purity WC powder (99.95% purity) with precise cobalt ratio
  • Isostatic pressing ensures uniform material density
  • Vacuum sintering controls grain growth for homogeneous fine-grained structure

Tungsten carbide (WC) is an ultra-hard ceramic material composed of tungsten and carbon, renowned for its exceptional hardness, wear resistance, and chemical stability. Its chemical formula is WC, with a hexagonal crystal structure and a high density of 15.6–15.8 g/cm³—nearly twice that of steel. It has an extremely high melting point of 2,870°C, ensuring excellent thermal stability. In terms of hardness, tungsten carbide has a Mohs hardness of 8.5–9, approaching that of diamond, and a Vickers hardness of 1,700–2,400 HV, far exceeding high-speed steel. Additionally, its thermal conductivity is 110 W/(m·K), providing outstanding heat dissipation, and it exhibits strong chemical inertness, resisting most acids and alkalis—though it is susceptible to hydrofluoric-nitric acid mixtures.
