White tungsten wire, tungsten bar forging, drawing made of fine wire.
White tungsten wire is mainly used in incandescent lamp, halogen tungsten lamp and other electric light source. Tungsten wires used as various luminators in light bulbs also need to be doped with a small amount of potassium, silicon and aluminum oxides in the smelting process. This tungsten wire is called DopedTungstenWire, also known as 218 tungsten wire or non-sagtungstenwire.
White tungsten wire is generally a variety of drawing die drawn. The main use is to manufacture filament and high speed cutting alloy steel, also used in optical instruments, chemical instruments and other functions.
