What is tungsten carbide powder? Tungsten carbide powder (WC) is the main raw material for producing carbide, chemical formula WC. Full name Wolfram Carbide, tungsten carbide powder for black hexagonal crystal, appearance with a metallic luster, hardness and similar to diamond, is a good conductor for electricity and heat. With a melting point of 2870℃, a boiling point of 6000℃, a density of 15.63g/cm³ (twice the density of the steel), microhardness 17300MPa, an elastic modulus of 710 GPa, compressive strength 56MPa, insoluble in water, hydrochloric acid, and sulfuric acid, but soluble in titanium carbide, with good rigidity, corrosion resistance and thermal conductivity (thermal expansion coefficient 6.9 10-6 / K, resistivity 19.2 10-6 Ω · cm), low oxidation resistance and reducibility. When the temperature rises to 500℃, WC is easily oxidized to tungsten oxide by air. Under certain conditions, WC will react with hydrogen peroxide solution; WC is soluble in nitric acid, hydrofluoric acid, and royal water. At high temperatures, the WC is decomposed into tungsten and carbon. Pure tungsten carbide is fragile. It can reduce brittleness if mixed with a small amount of titanium, cobalt, and other metals. Tungsten carbide, used as a steel cutting tool, often adds titanium carbide, tantalum carbide, or their mixtures to improve explosive resistance. Tungsten carbide is chemically stable.
Main uses of tungsten carbide powder Tungsten carbide powder mainly has the following three uses: 1. Raw material for the production of carbide. However, according to the different uses of alloy, the particle size of tungsten carbide is also different: superfine particle WC is used for finishing alloy; medium particle WC is used for roughly processed alloy and wear-resistant parts; and coarse particle WC is used for impact-resistant tools. 2. For spraying material with high density, high binding strength, large hardness, and low stomatal rate. 3. Prepare silver tungsten carbide electric contacts. Electric contact is an important part of the high-voltage circuit breaker, switch cabinet, disconnecting switch, and grounding switch.
