Tungsten wire is generally drawn from a variety of drawing die. The main purpose is to manufacture filament and high-speed cutting alloy steel, but also for optical instruments, chemical instruments and other aspects of the role.
It is also necessary to incorporate a small amount of potassium, silicon and aluminum oxides in the process of metallurgy, which is called DopedTungstenWire, also known as 218 tungsten wire or non-sagTungsten wire (Non-sagTungstenWire).
Tungsten wire is mainly used for incandescent, halogen and other electric light source.
