Product Description
Tungsten Wire
Tungsten wire has a high melting point, high resistivity, good strength and low vapor pressure. It is the best material for making incandescent filaments among all pure metal. Tungsten wire is generally drawn by various wire drawing dies. The main purpose is to manufacture filaments and high-speed cutting alloy steel, and it is also used in optical instruments, chemical instruments, etc.

Application of tungsten and tungsten alloy wire
Most of the tungsten filaments are used to make the filaments of various incandescent and tungsten halogen lamps and the electrodes of gas discharge lamps. People’s requirements for product quality and photoelectric parameter consistency of light bulbs are getting higher and higher, which requires us to improve the performance of tungsten wire by adding a small amount of other elements, so that it can meet the special requirements of certain fields.
