Making incandescent filament pure tungsten wire

Tungsten wire is mainly used in incandescent lamps, halogen tungsten lamps and other electric light sources. Tungsten wires used as various luminaries in also need to be mixed with a small amount of potassium, silicon and aluminum oxides in the smelting process, which is called doped tungsten wire (DopedTungstenWire), also known as 218 tungsten wire or Non-sagTungstenWire.

Tungsten wire is generally drawn by a variety of drawing dies. The main use is to manufacture filament and high-speed cutting alloy steel, but also used in optical instruments, chemical instruments and other aspects of the role.
