The melting point of tungsten is the highest of all metal elements, the density is high, and is close to the gold, the hardness of tungsten is also very high, the hardness of tungsten carbide is close to diamond. In addition, tungsten also has good electrical conductivity and thermal conductivity, low coefficient, which is widely used in alloy, electronics, chemical industry.
How Tungsten CAS 7440-33-7 is Used?
Alloy field
Tungsten is known for its high hardness, which enhances the strength, wear resistance and durability of steel. Tungsten is the main alloying element in a variety of steels such as high-speed steels, tungsten steels and tungsten-cobalt magnetic steels.
Tungsten carbide base hard alloy
Tungsten carbide tungsten carbide alloys are known for their high wear resistance and hardness, which is almost equal to that of diamond. These alloys are made by a powder metallurgical process using tungsten carbide powder and metal binders such as cobalt, nickel or molybdenum.
Heat and wear-resistant alloys
When combined with metals such as cobalt, chromium and carbon, tungsten forms alloys for high-strength, wear-resistant components such as engine valves, turbine impellers and rocket motor nozzles. These alloys are critical for aerospace and high-performance applications.
Electronic field
Tungsten is widely used in the electronics and power industries. Tungsten's long life and high light output make it commonly used in the production of light bulb filaments, including incandescent and halogen lamps. Tungsten filaments are also used in the manufacture of electron tubes, hot cathodes and other electronic instruments.
