Tungsten Wire

Tungsten wire used as various luminous materials in light bulbs also needs to be doped with a small amount of potassium, silicon and aluminum oxides in the smelting process. Such tungsten wire is called Doped Tungsten Wire, also known as 218 Tungsten Wire or Non-sag Tungsten Wire.

Tungsten wire is generally drawn by various wire drawing dies. It is mainly used in manufacturing filament and high-speed cutting alloy steel, also used in optical instruments, chemical instruments and so on.

Tungsten wire is mainly used in incandescent lamps, halogen tungsten lamps and other electric light sources. Tungsten wire used as various luminous materials in light bulbs also needs to be doped with a small amount of potassium, silicon and aluminum oxides in the smelting process. Such tungsten wire is called Doped Tungsten Wire, also known as 218 Tungsten Wire or Non-sag Tungsten Wire.
