What is the Cemented Carbide?

Tweet

Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace. Since the tungsten carbide particles and the metallic binder material is heated to the melting point of binder metal between degrees Celsius 1300 and 1500, the term “cemented” refers to the tungsten carbide particles being captured in the metallic binder material and “cemented” together, forming a metallurgical bond between the tungsten carbide particles and the binder (WC - Co), in the sintering process. The cemented carbide dies supplier tell us that carbide hardness depends on the content of hardening phase and grain size. The higher the content of Tungsten carbide powder and the smaller of the size the grain are, the greater the hardness is. The toughness of cemented carbide depends on the binder metal. The higher the content of binder metal is, the stronger the flexure strength is. The cemented carbide industry commonly refers to this material as simply “carbide”, although the terms tungsten carbide and cemented carbide are used interchangeably. The carbide hardness depends on the content of hardening phase and grain size. The higher the content of Tungsten carbide powder and the smaller of the size the grain are, the greater the hardness is. The toughness of cemented carbide depends on the binder metal. The higher the content of binder metal is, the stronger the flexure strength is In the next time of the News update, we will introduce deeply in cemented carbide, the application of the cemented carbide industrial that relate to the copper processing industrial, the cemented carbide die.
