W70Cu30 Tungsten Copper Alloy Bar High Thermal Conductivity
W70Cu30 Tungsten Copper Alloy Bar High Thermal Conductivity
Tungsten Copper Alloy Bar is tungsten and copper composites with excellent properties of tungsten and copper, such as heat resistance, ablation resistance, high strength, excellent thermal and electrical conductivity. wCu alloys are easy to process. wCu alloys are widely used in engine, electric power, electronics, metallurgy, aerospace, aviation and other industries. CIP forming, sintered tungsten skeleton and copper (silver) infiltration technologies 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.
