Tungsten Coil Wire for Vacuum Metallization

Tungsten coil wire is a special metal wire made of high-purity tungsten. It has excellent high-temperature resistance, mechanical strength, and chemical stability, so it is widely used in a variety of high-temperature applications.

Tungsten coil wire usually has a uniform diameter and good flexibility and can be used to make vacuum metallized coatings and heating elements, etc. In vacuum metallization equipment, tungsten coil wire is used to manufacture the evaporation source - evaporation filament in the equipment. Because tungsten coils have excellent thermal conductivity and high-temperature resistance, they are also used as the main material for high-temperature heating elements, such as heaters in vacuum furnaces and heating coils in furnaces, as well as heating elements in high-temperature experiments and materials research.

We can provide tungsten coiled wires, or process vacuum metallized evaporation filaments according to drawings, and can customize various shapes of tungsten filaments composed of single or multiple tungsten filaments. Our tungsten filament has the advantages of high hardness, high resistivity, low vapor pressure, small thermal expansion coefficient, high-temperature resistance, wear resistance, impact resistance, corrosion resistance, electrical and thermal conductivity, and long life.
