Product Description

W75Cu25 Copper Tungsten Alloy Bars For Electric Spark Electrode

Copper Tungsten Alloy Bars are composite material of tungsten and copper, which has excellent properties of tungsten and copper, such as heat resistance, ablation resistance, high strength, excellent thermal and electrical conductivity. wCu alloy is easy to process. Tungsten copper alloy is widely used in engine, electric power, electronics, metallurgy, aerospace, aviation and other industries. CIP molding, sintered tungsten skeleton and copper (silver) infiltration techniques are used to produce large size and special shape products of wCu composites containing 6-90% copper, such as electrical contacts, electrodes, refractory parts, heat sinks and rocket parts.
