Tungsten carbide powder in cemented carbide powder

wallpapers News 2021-01-27
Tungsten carbide powder is the main raw material for the production of cemented carbide, chemical formula WC. Full name, tungsten carbide powder is a black hexagonal crystal with a metallic lustre, hardness similar to diamond, and a good conductor of electricity and heat. 

Properties and uses of tungsten carbide powder
Tungsten carbide powder is a dark grey powder, which can be dissolved in a variety of carbides, especially in titanium carbide, which is highly soluble, forming TiC-WC solid solution. Another compound of tungsten and carbon is tungsten carbide. Tungsten carbide powder is mainly used to produce cemented carbide. In tungsten carbide powder, carbon atoms are embedded in the interstices of the tungsten metal lattice without destroying the original metal lattice, forming interstitial solid solutions, so it is also called interstitial (or intercalation) compound. Tungsten carbide can be prepared by heating tungsten carbide, a mixture of tungsten and carbon, at high temperature. The presence of hydrogen or hydrocarbons can accelerate the reaction. 
 
Cemented carbide is a hard material that is widely used as cutting tool materials and other industrial applications. It is composed of fine carbide particles, which are bonded to form a composite material through a binder metal. Cemented carbide usually uses tungsten carbide (WC), titanium carbide (TiC) or tantalum carbide (TaC) as aggregates. The reference to "tungsten carbide" in industrial settings usually refers to these cemented composite materials. In most cases, cemented carbide tools will leave a better surface finish on the parts, usually better than cutting tough materials such as carbon steel or high-speed steel, and can withstand higher temperatures and stronger wear resistance than standard high-speed. Tungsten carbide is suitable for mechanical processing at high temperatures and can be used to make cutting tools, structural materials for kilns, jet turbines, nozzles, etc. Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibres, graphite, glass, stone and ordinary steel, and can also be used for cutting Hard-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc.
