W75Cu25 Tungsten Copper Welding Rods For High Arc Resistance
Tungsten Copper Welding Rods are a composite of tungsten and copper, which has excellent properties of tungsten and copper, such as heat resistance, ablation resistance, high strength, excellent thermal conductivity and conductivity. Tungsten copper alloys are easy to machine. Tungsten copper alloys are widely used in engine, power, electronics, metallurgy, aerospace and aviation industries. Using CIP molding, sintered tungsten skeleton and copper (silver) infiltration technology, tungsten copper composite products with large size and special shape containing 6-90% copper, such as electrical contacts, electrodes, refractory parts, radiators and rocket components, are produced.
