Carbide material is an alloy of a refractory metal bonded hard metal compound by powder metallurgy process.Cemented carbide has high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at a temperature of 500 ℃ also remained unchanged at 1000 ℃ still very high hardness.Carbide is widely used as a tool material, such as turning, milling, planer, drill, boring knives for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut material difficult to process heat-resistant steel, stainless steel, high manganese steel, tool steel.Carbide has high hardness, strength, wear resistance and corrosion resistance, known as "dental industry", used in the manufacture of cutting tools, cutting tools and wear parts cobalt, widely used in military, aerospace , mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction, etc., with the development of downstream industries, carbide increasing market demand. Future high-tech weaponry and equipment manufacturing, as well as rapid progress in the development of cutting-edge science and technology of nuclear energy, will greatly increase the demand for high-tech and high stability of cemented carbide products.
