Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy process. It has a series of excellent hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance, etc. The properties, especially its high hardness and wear resistance, remain basically unchanged even at a temperature of 500°C, and still have a high hardness at 1000°C. Cemented carbide has high hardness, strength, wear resistance and corrosion resistance, and is known as "industrial teeth". It is used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts. With the development of downstream industries, hard The market demand for high-quality alloys continues to increase. In the future, the manufacturing of high-tech weapons and equipment, the advancement of science and technology, and the rapid development of nuclear energy will greatly increase the demand for cemented carbide products with high technology content and high quality stability.
