Cemented carbide  is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at the temperature of 500 DEG C also remained unchanged, at 1000 DEG C still has very high hardness.          

Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials

Commented carbide is also widely used in mines and groud engaging.
