Twisted pure tungsten wire is applied for making heater elements and other heater components in semiconductor and vacuum devices. Tungsten heater wire made from tungsten wire W3a is with high thermal conductivity, good corrosion- resistant, nice breaking-resistant and long life for vacuum evaporation.
Tungsten heater, made of tungsten wires, have high melting point and good corrosion resistance. Tungsten heater wire is mainly used for vacuum metalizing, 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
Usually tungsten heater wire is used as evaporator (heating element) in the vacuum evaporation process to coat thin film on surface of mirrors, kinescope, toys, home appliance, machine and various decoration, etc
