Application field of tungsten wire

Tungsten wire is widely used. The following are some common uses:

1. Electronics industry: Tungsten wire is usually used to manufacture electronic devices, such as heaters in electron tubes, electron guns, and semiconductor devices. Its high melting point and good electrical conductivity make it an important material in electronic equipment.

2. Lighting: Tungsten wire is used to make filaments, such as incandescent bulbs and halogen bulbs. When current passes through tungsten wire, it emits bright incandescent light, so it is common in lighting applications.

3. Vacuum technology: Due to its high melting point and low evaporation rate, tungsten wire is widely used in vacuum tubes and vacuum equipment. It can be used as a hot cathode and vacuum sealing material.

4. Welding and cutting: Tungsten wire is used as an electrode material in welding and cutting processes such as TIG (argon arc welding) and laser cutting because it can withstand high temperatures and arc corrosion.

5. Medical equipment: Tungsten wire is also used in some medical equipment, such as cathodes for X-ray tubes and medical imaging equipment.

In general, the high temperature stability and electrical conductivity of tungsten wire make it an important material in various application fields.
