Top Suppliers Tungsten Steel Pipes - Tungsten Wire Filaments Supplier – WINNERS Detail:

Product Description

The resistivity of tungsten filament is 5.3*10^-8. Tungsten 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 metals. Tungsten wire is generally drawn by various drawing dies. The main purpose is to manufacture filament and high-speed cutting alloy steel, and also used in optical instruments, chemical instruments and so on.

Application

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.
