摘要: Cemented carbide material comprising 10 to 60% by weight of tungsten carbide, 5 to 40% by weight of titanium carbide, 5 to 30% by weight of tantalum carbide, 3 to 20% by weight of titanium nitride and 5 to 20% by weight of an iron family metal such as cobalt, nickel or iron. The cemented carbide material may further contain 5 to 20% by weight of molybdenum and/or molybdenum carbide. The material is excellent in heat resistance, wear resistance, hardness and toughness and is adapted for a wide variety of cutting conditions.
