It is the perfect material for thin film applications. Its high level of electrical conductivity and low diffusion into adjacent layers make tungsten an important component in thin-film transistors. Tungsten is found everywhere where it is worked at high temperature. No other metal can compete with tungsten when it comes to heat resistance. Tungsten has the highest melting point of all metals, making it also suitable for applications with very high temperatures. It is also characterized by its extraordinarily low coefficient of thermal expansion and high dimensional stability.
