Wolfram tråd
Tungsten wire 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 mixed 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 use is to make filaments and high-speed cutting alloy steel, and it is also used in optical instruments, chemical instruments and other aspects.
