Tungsten Rod

Tungsten rod can be divided into two categories: one is used for finished products, the other is semi-finished rough bar for stretching wires, the processing methods of which include rotary forging and groove rolling. We own exquisite processing technology. Our tungsten rod/bar has the advantages of high electrode strength, high oxidation temperature resistance, long service life and strong corrosion resistance.

Our company can produce tungsten rods of any length according to customer’s drawings. The surfaces of tungsten alloy rods are chemically cleaned to remove all lubricants and oxides. Tungsten rods are mainly used as heaters, support columns, feeders and fasteners in high temperature furnaces in vacuum or reduction environment. They are also applied in the light source of illumination industry, the electrode and rare earth melting in the glass industry, and welding equipment.

Tungsten rods can be made into tungsten wires. Due to the high hardness, low mechanical wear, and resistance to fusion, tungsten materials are widely used for electrical contacts in the electrical systems of automobile distributors, automobile engine voltage regulators and so on. Besides, tungsten rods can be used for electrodes, electric tube bars, side bars, supply wires, brackets, gas lamp electrodes, high-power incandescent filaments, filaments of electronic tubes and cathodes of emission tubes, crankshafts of advanced vehicles, etc.
