Send InquiryAdvantages of tungsten heating wire
Tungsten has the lowest vapour pressure and the lowest coefficient of thermal expansion of all metals in pure form.
The electrical conductivity is good, about 30% of copper, as well as the thermal conductivity, which is about 43% that of copper. Tungsten has the lowest coefficient of thermal expansion, and at temperatures above 1650 °C the highest tensile strength of all metals. Tungsten has unusually low specific heat, which combined with the good thermal conductivity means that the metal heats up and cools down very quickly. That is a benefit with a fine tungsten wire.
