Tungsten wire is produced by stretching the Tungsten rod to the required diameter under swaging process. With the properties of hardness, low mechanical abrasion and melting resistance, Tungsten rod/bar is widely applied to electrical contacts which can be used for electrical appliances of vehicles equipped, voltage regulator in automobile engine and other electrical systems. In addition, Tungsten rod/bar can be widely used in electrode, the gate pole in electronic tube, side rod, lead-lines, frame, gas lamp electrodes, high-power incandescent filament, the filament in electronic tube and cathode in launch tube, cylinder barrel of advanced automobile etc.
