Tungsten Copper Rod Properties
Tungsten Copper Rod Properties
Tungsten copper rod combines the advantages of tungsten and copper, with a high melting point of tungsten (tungsten melting point of 3410 ℃, copper melting point 1080 ℃), high density (tungsten density of 19.25g / cm, copper density of 8.92 / cm3); excellent thermal conductivity properties of copper, tungsten copper alloy (composition generally ranges WCu7 ~ WCu50) have uniform microstructure, high temperature, high strength, resistance to arc erosion, high density; moderate conductivity, thermal conductivity, high temperature materials are widely used in military, high-voltage switch with electrical alloy, EDM electrode, microelectronic materials, parts and components as widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.
