Product Description
W-Cu a combination of metal alloy of tungsten and copper the advantages, including high melting point of tungsten (W melting point of 3410, iron melting point 1534 ), high density (density of tungsten 19.34G/cm3, the density of iron for 7.8g/cm3); Copper (silver) thermal conductivity superior performance, W-Cu alloy (Composition for the general scope of WCu7 ~ WCu50) uniform microstructure, high temperature, high strength, resistance arc ablation, density; Conductive, thermal conductivity properties of moderate, is widely used in high temperature materials, high-voltage electrical switch alloy, EDM electrodes, microelectronics materials, as parts and components are widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.
Tungsten, copper mainly composed of elements of a two-phase structure of false alloys, metal matrix composites. Because of copper and tungsten different physical properties can't be used casting method of production, is now generally used to obtain powder alloy technology. Preparation of powder metallurgy method using W-Cu alloy process for the ingredients mixed - suppress molding - Sintering Solubilization dialysis - cold.
