Tungsten wire is a slender metal wire made of tungsten (element symbol W). Tungsten is a chemical element with a very high melting point, approximately 3422 degrees Celsius (6192 degrees Fahrenheit), which allows it to remain stable in high-temperature environments. Due to its excellent high-temperature stability and conductive properties, tungsten wire is widely used in many fields, including electronics, power, lighting, battery manufacturing, semiconductor industry, and vacuum equipment.
In lighting applications, tungsten wire was once an important element in traditional incandescent light bulbs because of its ability to emit light at high temperatures, producing visible light. However, with the rise of new lighting technologies such as LED, incandescent bulbs are gradually being phased out, but tungsten wires still play an important role in other fields.
In the electronics industry, tungsten wire is used to make electronic devices and vacuum tubes because of its ability to operate in high vacuum environments without damage. In the power industry, tungsten wire is used to make resistance wire, which is used in heating elements and resistors. Additionally, tungsten wire is used as a material for electron beam melting and electron beam processing in semiconductor manufacturing.
