Cemented carbide has a series of high-quality properties such as high strength, wear resistance, good compressive strength and ductility, high temperature resistance, corrosion resistance, etc. It is very important for its high toughness and wear resistance, even at a temperature of 500 ℃. It remains unchanged, and still has high strength at 1000°C. Cemented carbide is commonly used as a tool material, such as lathe tools, turning tools, planers, twist drills, boring tools, etc., for cutting pig iron, rare metals, plastics, chemical fibers, high-purity graphite, laminated glass, marble and general stainless steel plates It can also be used to cut materials that are difficult to produce and process, such as heat-resistant steel, stainless steel, high manganese steel, and tool steel. Nowadays, the cutting speed of new carbide CNC inserts is hundreds of times that of alloy steel.

Carbide rotary files can also be used to make drilling tools, mining tools, exploration tools, precision measuring instruments, wear-resistant parts, metal material molds, cylinder linings, precision bearings, nozzles, metal molds (such as metal wire drawing) For molds, anchor bolt molds, nut molds, and various standard parts molds, the high-quality properties of cemented carbide gradually replaced the previous steel molds).
