An alloy composed of tungsten and copper. The copper content of commonly used alloys is 10% to 50%. The alloy is prepared by powder metallurgy and 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 liquefies and evaporates, absorbing a large amount of heat and reducing the surface temperature of the material. Therefore, this type of material is also called metal sweating material.
Tungsten copper bar details
Features
Tungsten copper rod is a composite material made by utilizing the excellent metallic properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder through static pressure molding, high-temperature sintering, and copper dissolution. It has good arc-breaking performance, good electrical and thermal conductivity, small thermal expansion, no softening at high temperatures, high strength, high density, and high hardness.
use
Tungsten copper alloy has a wide range of uses, mainly used to manufacture contacts of high-voltage electrical switches that are resistant to arc ablation and high-temperature components such as rocket nozzle throat linings and tail rudders. It is also used as electrodes for electrical machining, high-temperature molds and other Situations requiring electrical and thermal conductivity and high temperature use.
Tungsten-copper alloy has the advantages of both tungsten and copper, including high temperature resistance, arc ablation resistance, high strength, heavy specific gravity, good electrical and thermal conductivity, small thermal expansion, easy cutting and processing, and good sweat cooling performance.
