High Thermal Conductivity Tungsten Copper 75/25 Cuw Rods
Product Description
Tungsten Copper 75/25 Cuw Rods has a wide range of uses, mainly used to manufacture high-temperature components such as the contacts of high-voltage electrical switches that resist arc ablation, rocket nozzle throat linings, and tail rudders, as well as electrodes for electrical machining, high-temperature molds and other Applications requiring electrical and thermal conductivity and high-temperature use.
Tungsten Copper 75/25 Cuw Rods combines the advantages of metal tungsten and copper. Among them, tungsten has a high melting point (the melting point of tungsten is 3410°C, the melting point of copper is 1080°C), and the density is high (the density of tungsten is 19.25g/cm, and the density of copper is 8.92/cm3); Copper has excellent electrical and thermal conductivity. Tungsten-copper alloy (general range of composition is WCu7~WCu50) has uniform microstructure, high-temperature resistance, high strength, arc ablation resistance, high density; moderate electrical and thermal conductivity, and is widely used in military high-temperature materials, Electrical alloys, electrical machining electrodes, and microelectronic materials for high-voltage switches are widely used as parts and components in the aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment, and other industries.
