What are the application fields of tungsten

Tungsten is a rare metal that looks like steel. Because of its high melting point, high hardness, excellent corrosion resistance, and good electrical and thermal conductivity, it has become one of the most important functional materials in modern industry, national defense, and high-tech applications. What are the specific application fields of tungsten?

● Alloy Field

Due to its high hardness and high density, tungsten is an important alloy element because it can significantly improve the strength, hardness and wear resistance of steel. It widely uses in the production of various steel materials. Common tungsten-containing steel materials are high-speed steel, tungsten steel, and tungsten-cobalt magnets are mainly used to manufacture various tools, such as drill bits, milling cutters, female molds and male molds, etc.

Tungsten cathode filaments

● Electronic Field

Tungsten has strong plasticity, low evaporation rate, high melting point and strong electron emission ability, so it is widely used in electronics and power supply industries. For example, tungsten wire has high luminous rate and long service life, and is often used to manufacture various bulb filaments, such as incandescent lamps, iodine-tungsten lamps, etc. In addition, tungsten wire can also be used to manufacture direct-heated cathodes and grids of electronic oscillating tubes and cathode heaters in various electronic instruments.

● Chemical Field

Tungsten compounds are commonly used in the production of certain types of paints, pigments, inks, lubricants and catalysts. For example, sodium tungstate is often used in the manufacture of metal tungsten, tungstic acid and tungstate, as well as dyes, pigments, inks, electroplating, etc.; tungstic acid is often used as a mordant and dye in the textile industry, and used in the chemical industry to prepare high Catalyst for octane gasoline; tungsten disulfide is often used in organic synthesis, such as solid lubricant and catalyst in the preparation of synthetic gasoline; bronze-colored tungsten oxide is used in painting.

● Medical Field

Due to its high hardness and density, tungsten alloys are very suitable for medical fields such as X-ray and radiation protection. Common tungsten alloy medical products include X-ray anodes, anti-scatter plates, radioactive containers and syringe shielding containers, etc.


● Military Field

Due to its non-toxic and environmentally friendly properties, tungsten products have been used to replace the previous lead and depleted uranium materials to make bullet warheads, so as to reduce the pollution of military materials to the ecological environment. In addition, due to its strong hardness and high temperature resistance. Tungsten can make the prepared military products more superior in combat performance. Tungsten products used in the military mainly include: Tungsten alloy bullets, kinetic energy armor-piercing bullets.

In addition to the above fields, tungsten can also be used in aerospace, navigation, atomic energy, shipbuilding, automobile industry and other fields.
