What is tungsten carbide powder? Tungsten carbide powder (WC) is the main raw material for producing cemented carbide, chemical formula WC. Its full name is. Tungsten carbide powder is a black hexagonal crystal with metallic lustre and hardness similar to diamond. It is a good conductor of electricity and heat. Its melting point is 2870 ℃, its boiling point is 6000 ℃, and its relative density is 15.63 (18 ℃). Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid and soluble in nitric acid and hydrofluoric acid mixed acid. Pure tungsten carbide is fragile, and if a small amount of titanium, cobalt and other metals are mixed, It can reduce brittleness. As a steel cutting tool, tungsten carbide is often added with titanium carbide, tantalum carbide or their mixture to improve the antiknock ability. The chemical properties of tungsten carbide are stable. Tungsten carbide powder is dark grey powder, which can dissolve in various carbides, especially in titanium carbide, forming TiC-WC solid melt.
Application of tungsten carbide powder Nanometer tungsten carbide is applied to composite materials to improve their performance: Nanometer tungsten carbide cobalt composite powder is the main raw material for preparing high-performance cemented carbide and wear-resistant coating Nanometer tungsten carbide cobalt composite powder shows good effects as wear-resistant coating material. The coating prepared by rapid melting and condensation thermal spraying technology can maintain the nanostructure characteristics of the powder, thus significantly improving the performance of the wear-resistant coating of cemented carbide. The nano tungsten carbide cobalt composite powder products produced in China have been used to prepare cemented carbide and wear-resistant coating Such as: cutting tools, computers, machinery and other industries; Tungsten carbide is suitable for machining under high temperatures and can be used to make cutting tools, structural materials of kilns, jet engines, gas turbines, nozzles, etc.
Harm of tungsten carbide powder to human body The hazards include that tungsten dust can cause peribronchitis, peribronchiolitis, atresia bronchiolitis and atrophic emphysema. Tungsten carbide can cause the proliferative reaction of lymph tissue cells in the lung and gradually appear hardening. The blood vessel wall is thickened and homogenized. Those exposed to tungsten carbide dust at work suffer from gastrointestinal dysfunction, kidney irritation and catarrhal inflammation of the upper respiratory tract
Price of tungsten carbide powde Tungsten carbide powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of tungsten carbide powder. A large amount of large amount will be lower. The Price of tungsten carbide powder can be found on our company's official website.
