The thermal expansion coefficient of tungsten wire is about 4.5×10^-6/℃. The thermal expansion coefficient describes the ratio of the change in length, volume or area of an object when the temperature rises to the original length, volume or area. Since tungsten wire has a small thermal expansion coefficient, its size changes relatively little when the temperature changes, which helps to maintain the stability and reliability of lighting equipment such as halogen lamps.
