What is Tungsten? Tungsten is a gray-black metal with metallic luster (body-centered cubic crystal). The melting point is 3400℃. The boiling point is 5555℃. The hardness of tungsten is the hardest among metals. The hardness of sintered tungsten bar is 200 ~ 250, and that of the rotary hammer tungsten bar is 350~400. Mixed acid is soluble in nitric acid and hydrofluoric acid. Melted with a mixture of sodium hydroxide and sodium carbonate. Slightly soluble in nitric acid, sulfuric acid, and aqua regia; Insoluble in water, hydrofluoric acid, and potassium hydroxide.
Classification of tungsten powder There are two variants of tungsten, A and B. At standard temperature and normal pressure, Type A is a stable body-centered cubic structure. Type B tungsten can only appear in the presence of oxygen. It is stable below 630℃, and it is converted to tungsten A above 630℃, and this process is irreversible. Usesof Tungsten Powder Tungsten is mostly used to produce cemented carbide and ferrotungsten. A heat-resistant and wear-resistant alloy composed of tungsten, chromium, molybdenum, and cobalt is used to make cutting tools, metal surface hardening materials, gas turbine blades, combustion tubes, etc. It is a refractory alloy with tantalum, niobium, and molybdenum. Tungsten and tungsten-silver alloys are used as materials for electrical contacts. High-density W-Ni-Cu alloy is used as a shield against radiation. Tungsten wires, rods, sheets, etc., are used to make parts of electric bulbs, electronic tubes, and electrodes for arc welding. Tungsten powder can be sintered into filters with various porosities. FW-1 is used as raw material for large slabs and tungsten-rhenium galvanic couples. FW-2 is used as a contact alloy and high-specific gravity shielding material. FWP-1 is used for plasma spraying materials. Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into processed materials such as wires, rods, tubes, plates and products with certain shapes. Tungsten powder can be mixed with other metal powders to make various tungsten alloys, such as W-Mo alloy, W-Re alloy, W-Cu alloy, and high-density W alloy. Another important application of tungsten powder is to make tungsten carbide powder and then to prepare cemented carbide tools, such as turning tools, milling cutters, drill bits, and dies. Price of Tungsten powder Tungsten powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Tungsten powder. A large amount of large amount will be lower. The price of Tungsten powder can be found on our company's official website. Tungsten powder supplier Luoyang Tongrun Nano Technology Co. Ltd.
