    Tungsten wire is made from tungsten bar by forging and drawing. The resistivity of tungsten wire is 5.3 * 10 ∧-8, and tungsten wire is mainly used for incandescent lamp, halogen tungsten lamp and other lighting source because of its high melting point, high resistivity, good resistance and low vapor pressure. When producing tungsten wire, mixing a little quantity of potassium, silicon or aluminum oxide, could prevent the wire from droop, and also improve the performance of the lamp filament. The tungsten wire is usually drawn with a variety of drawing die. Except for lamp filament in lighting source, tungsten wire is also used for vacuum tube filament, heating wire in high temperature furnace, heating element of vacuum coating and optical instruments, chemical apparatus, etc.
