5. Product Feature: High melting point, High-density, high temperature oxidation resistance, long service life, resistance to corrosion..

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.
