Tungsten wire

The resistivity of tungsten is 5.3 * 10 ^ -8, high melting point of tungsten, resistivity, strength, vapor pressure, is all pure metals, the production of incandescent filament tungsten best material. With the development of science and technology, theprogress of human civilization, the requirements of life getting higher and higher,more and more close to nature. Had phased out incandescent tungsten done,replaced by fluorescent lamps. Fluorescent lamps not only can emit white light nearthe sun's rays, but also energy saving, energy-saving lamps in China.
Tungsten is now still widely used in the heating industry, because the tungsten resistivity and high temperature resistance determines the popularity of tungsten inthe heating industry.
