Applications of Tungsten Carbide

Tungsten carbide has a series of excellent performances. It has high hardness, abrasion resistance, good strength and toughness, heat resistance and corrosion resistance etc. Especially its high hardness and wear resistance, even at 500in temperature are basically unchanged and at 1000 it still has very high hardness. Carbide is extensively used to make tools and cutters. For example, turning inserts, milling inserts, shaping inserts, boring cutters, and drilling bits etc are made of carbide. They are used to process rough and semi-finishing of cast iron, non-ferrous metals, plastic, fiber, graphite, glass, stone and ordinary steel, and also can be used to process heat-resistant steel, stainless steel, high-manganese steel, tool steel and other materials which are difficult to process. Nowadays, the cutting speed of new cemented carbide tools is several hundred times higher than that of carbon steel.
