Product Introduction

What is WCu round bar?

WCu round bar is a composite metal of tungsten and copper, which combines many excellent properties of metal tungsten and copper, among which tungsten has a high melting point and high density; copper has excellent electrical and thermal conductivity. Tungsten-copper alloy (composition generally ranges from WCu7 to WCu50) has uniform microstructure, high-temperature resistance, high strength, arc ablation resistance, and high density; moderate electrical and thermal conductivity, widely used in military high-temperature resistant materials, electrical alloys for high-voltage switches, Electrodes for electrical processing and microelectronic materials are widely used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment, and other industries as parts and components.

Application of WCu round bar


The advantages of WCu round bar are high-temperature resistance, high-temperature strength, arc ablation resistance, good electrical and thermal conductivity, and fast heat dissipation. Applications focus on EDM electrodes, resistance welding electrodes, and high voltage discharge tube electrodes.

Electric machining electrodes are characterized by a wide variety of specifications, small batches, and large total quantities. The WCu round bar used as an electrical machining electrode should have the highest possible density and uniformity of organization, especially for slender rod-shaped, tubular, and special-shaped electrodes.
