Tungsten wire introduction
According to the different cross-sectional shapes, tungsten wire can be divided into tungsten round wire, tungsten flat wire, tungsten square wire, etc. Tungsten wire is usually drawn by various wire drawing dies.
Tungsten wire is mainly used to make filaments and high-speed cutting alloy steel, and is also used in optical instruments, chemical instruments, etc.
The resistivity of tungsten wire is 5.3*10^-8. Tungsten has a high melting point, high resistivity, high strength and low vapor pressure. It is the best material for making incandescent filaments among all pure metals.
Tungsten wire application
In addition to a small amount of tungsten wire used as a heating material for high-temperature furnaces, thermistors for electron tubes, and reinforcements for composite materials, most tungsten wires are also used to make filaments for various incandescent lamps and halogen lamps, as well as electrodes for gas discharge lamps.
