What Is Pure Tungsten Wire?

Pure tungsten wire refers to tungsten wire made of extremely pure tungsten material. Tungsten is a chemical element with a very high melting point (approximately 3422 degrees Celsius or 6192 degrees Fahrenheit) and excellent high-temperature stability. Due to its excellent properties, tungsten is widely used in high temperature and special environment applications.

Pure tungsten wire is usually manufactured by heating and stretching high-purity tungsten material into filaments. These filaments can be of different diameters to meet the needs of different applications. The characteristics of pure tungsten wire include:

High temperature stability: Pure tungsten wire has excellent high temperature stability and can maintain structural integrity and mechanical properties at extremely high temperatures, which makes it widely used in high temperature environments.

High melting point: Tungsten is a high melting point metal, so pure tungsten wire can be used at very high temperatures, such as in applications such as high-temperature furnaces, vacuum equipment, and high-temperature heaters.

Low thermal expansion coefficient: The thermal expansion coefficient of pure tungsten wire is relatively low, which means that it changes in size less during heating and cooling, helping to maintain the stability of the device.

Good electrical conductivity: Although pure tungsten is a metal, it has relatively poor electrical conductivity at room temperature. Therefore, in some applications, especially where high electrical conductivity is required, other alloy tungsten wires may be chosen, such as tungsten-copper alloy.
