Tungsten filaments, made of tungsten wires, have high melting point and good corrosion resistance. They are mainly used for vacuum metallizing, such as heating elements. For chrome scope, mirrors, plastics and decoration articles. Tungsten filaments can be stranded into single or several wires according to the samples Or drawings of customers. Pure wire and doped wire are both available. Diameter of tungsten wire: 0.55---2.0mm

Tungsten wire is used as vacumme material.
Tungsten filament is applied as evaporator(heating element)in the vacuum metalizing

Twisted tungsten wires are made of selected high quality material of tungsten, with the properties of excellent thermal conductivity, finely processed, and long duration.
Usually twisted tungsten filament are used as evaporator (heating element) in the vacuum metalllizing(evaporation) process to coat thin film on surface of mirrors, kinescope, toys, home appliance, machine and various decoration, etc.
