Hard alloy is an alloy material made of hard compound of refractory metal and bonding metal by powder metallurgy.
Cemented carbide with high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even at 500 ℃ temperature basic remains the same, there are still very high hardness at 1000 ℃.
Hard alloy is widely used as tool material, such as turning tool, milling cutter, planer, drill bit, boring cutter, etc., used for cutting cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel, also can be used for cutting heat resistant steel, stainless steel, high manganese steel, tool steel and other difficult materials.
Cemented carbide with high hardness, strength, abrasion resistance and corrosion resistance, known as the "teeth" industry, used in the manufacture of cutting tool, cutting tool, cobalt and wear-resistant parts, widely used in the military-industrial complex, aviation, machinery, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, along with the development of downstream industries, carbide increasing market demand. In addition, the future high-tech weapon and equipment manufacturing, the progress of cutting-edge science and technology and the rapid development of nuclear energy will greatly increase the demand for cemented carbide products with high technical content and high quality stability.
