3. Manufacturing processes

The processing of tungsten wire is very difficult, because it is prone to heat softening, so special equipment is required for processing;

The manufacture of tungsten wire requires the use of highly pure tungsten powder. Firstly, the pure tungsten powder is pressed into strips, then heat-treated at high temperature to make it into single crystal tungsten, and finally drawn into wire;

The manufacturing process of tungsten wire also requires processing processes such as polishing and surface cleaning to ensure the appearance and surface finish of the wire.
