Tungsten wire is made of refractory metal tungsten, which has high melting point, high resistivity, good strength and low vapor pressure, and is widely used in the field of lighting. Its high-temperature performance is critical for the production of lighting products and other products.

Except for a small amount of tungsten wire used as heating material in high temperature furnace, heating body of electronic tube and reinforcing rib of composite material, most of it is used to make filament of various incandescent lamps and tungsten halogen lamps, and electrodes for gas discharge lamps.

Tungsten wire with the thick specification is usually processed and cut into several bars after straightening, and is widely used in the lighting and electronics industries as glass-to-metal sealing elements.

However, with the continuous shrinking of the traditional lighting application market in recent years, China’s domestic leading tungsten companies are more actively exploring other application fields, such as photovoltaics. Thin tungsten wire has the advantages of high tensile strength, high stiffness, good toughness, low torsional stress, fatigue resistance, corrosion resistance, etc., and can replace carbon steel wire.
