News Guide: the hard refractory metal compounds and bonding metal by powder metallurgy process is made of an alloy material. Carbide with 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 500 ℃ temperature also remained unchanged , at 1000 ℃ still very high hardness.A refractory hard metal compound and a bonding metal by powder metallurgy process made of an alloy material. Carbide with 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 500 ℃ temperature 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 heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to Molybdenum crucible materials. Carbide cutting tools are now new carbon steel equal number of times.
Carbide with high hardness, strength, wear resistance and corrosion resistance, known as the "industrial teeth", for the manufacture of cutting tools, cutting tools, drilling tools and wear parts, widely used in military, aerospace , machining, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, carbide market demand is increasing continuously. . And future high-tech weapons and equipment manufacturing, advanced scientific and technological progress as well as the rapid development of nuclear energy, will greatly improve the stability of high-tech and high-quality carbide products. According to the analysis, from the "2013-2017 China Cemented Carbide Industry Market Outlook and Investment Analysis Strategic Planning Report," 2015 production will reach our carbide 30,000 tons of industrial output value reached about 23 billion yuan.
Feature
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
