Tungsten carbide powder metallurgy materials are commonly used in high-quality, high-precision, high-efficiency, and automated mass-produced cutting tools.
Tungsten carbide materials are not a single specification, but can be selected in different grades according to tungsten carbide particle size, cobalt content, hardness, toughness, and actual machining requirements.
Common tungsten carbide materials for metalworking include:
Ultrafine particles + approximately 10% Co
For example, Sumitomo AF308:
• Common hardness approximately HRA 93.5
Ultrafine particles + approximately 12% Co
For example, Sumitomo AF312:
• Common hardness approximately HRA 92.1
Ultrafine particles + approximately 10% Co
For example, Sumitomo AF510, AF810:
• Common hardness approximately HRA 92.3
Ultrafine particles + approximately 13% Co
For example, Sumitomo AF813:
• Common hardness approximately HRA 91.1
The above are just examples of material applications. The actual grade, hardness, toughness, and application range of tungsten steel should be selected based on the material specifications of the tool manufacturer and the actual processing requirements.
