Tungsten copper is thermostability and the characteristics of arc burning resistance, so if tungsten copper is as a contact switch, tungsten copper has the incomparable advantage of other metal material in high power high current vacuum switch, fluid resistance soft starter, large current relay device. Tungsten copper is high density, low gas content, the relative higher proportion in the application requirements.
