Copper tungsten alloy products

Tungsten and copper alloy. Commonly used alloys contain 10% to 50% copper. The alloy is prepared by powder metallurgy, which has good electrical and thermal conductivity, good high-temperature strength and certain plasticity. At very high temperatures, such as above 3000°C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. So this kind of material is also called metal sweating material.

Tungsten copper alloy has a wide range of uses, mainly used to make the contacts of high-voltage electrical switches that resist arc ablation, rocket nozzle throat linings, tail rudders and other high-temperature components, as well as electrodes for electrical machining, high-temperature molds and other Applications requiring electrical and thermal conductivity and high-temperature use. Widely used in military high temperature resistant materials, electrical alloys for high voltage switches, electrical machining electrodes, microelectronic materials, as parts and components. Such as: aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries.
