Cemented carbide has a series of excellent properties, such as high hardness, abrasion resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wears resistance, which basically remain unchanged even at the temperature of 500℃, but still have a high hardness at 1000℃.
Cemented carbide, also known as tungsten steel, is made of high quality tungsten carbide + cobalt powder by pressing and sintering after the mixture of formula ratio, with high hardness, high strength, high wear resistance, and high elastic modulus, belonging to the powder metallurgy industry. As the teeth of modern industry, cemented carbide cutting tools play a fundamental role in promoting the development of the manufacturing industry.
According to the size of the grain, cemented carbide can be divided into ordinary cemented carbide, fine-grained cemented carbide, and subline-grained, ultra-fine-grained cemented carbide. According to the main chemical components, it can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide.
Titanium carbide base cemented carbide is Tic as the main component, commonly used metal bonding Mo and Ni. Cemented carbide has a high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC), second only to diamond, and good thermal hardness (up to 900 ~ 1000℃, maintaining 60HRC). High bending strength (MPa5100), good impact toughness and high corrosion resistance, chemical inertness, and other properties not found in ordinary alloy blades.
