Tungsten wire is a fine wire made by forging and drawing the tungsten bar.

Tungsten wire is mainly used in incandescent lamp, halogen lamp and other electric light sources. A small amount of potassium, silicon and aluminum oxides need to be added into the tungsten wire used as various luminescent substances in the bulb. This kind of tungsten wire is called doped tungsten wire, also known as 218 tungsten wire or non drooping tungsten wire-

Tungsten wire is usually drawn by various drawing dies. The main purpose is to manufacture filament and high speed cutting alloy steel, also used in optical instruments, chemical instruments and other aspects of the role.
