Description:
Tungsten filament is a thin filament made by forging and drawing
tungsten bars.
Tungsten filament is mainly used in electric light sources such as
incandescent lamps and halogen tungsten lamps. Tungsten wire used
as various luminous bodies in light bulbs also needs to be doped
with a small amount of potassium, silicon and aluminum oxides
during the smelting process. This kind of tungsten wire is called
doped tungsten wire (Doped Tungsten Wire), also known as 218
tungsten wire or non-sag tungsten wire (Non-sag Tungsten Wire).
Tungsten wire is generally drawn by various wire drawing dies. The
main purpose is to make filaments and high-speed cutting alloy
steel. It is also used in optical instruments, chemical instruments
and other aspects.
