Tungsten copper tellurium contact is a high-performance electrical contact material, which provides a series of superior performance by combining the characteristics of tungsten, copper and tellurium. This material is commonly used in the electrical contacts of high-voltage electrical switches, especially in vacuum switching appliances. The tungsten-copper-tellurium contact inherits many advantages of tungsten and copper, such as high temperature resistance, arc ablation resistance, high strength, high specific gravity, excellent electrical and thermal conductivity, etc. In addition, it also has excellent thermal expansion, easy cutting and sweat cooling characteristics. The arc ablation performance of tungsten copper tellurium contacts is particularly excellent, thanks to the high melting point of tungsten and the high conductivity of copper, and the addition of tellurium can further optimize its performance. The addition of a small amount of tellurium can improve the performance of the material in some applications where a low shut-off value is required. This contact material also has high thermal stability and high temperature resistance, so that it can maintain stable electrical and mechanical properties in high temperature environments.

In the preparation process, the tungsten copper tellurium contact material usually adopts the powder metallurgy process, including the combination of powder mixing pressing sintering and infiltration process, to ensure the high density and excellent performance of the material. In addition, the physical properties of tungsten copper tellurium contacts include high melting point, high density, high hardness, good plasticity, low thermal expansion coefficient, excellent high temperature resistance and corrosion resistance. Due to its unique physical and chemical properties, tungsten-copper-tellurium contacts are not only widely used in the electrical field, such as high-voltage electrical appliances, circuit breakers, switches, contactors and other equipment, but also in the electronic field, such as electronic connectors, semiconductor packaging, etc., as well as high-temperature stoves and thermal equipment in the fields of metallurgy and chemical industry. With the continuous progress of science and technology and the rapid development of industry, the application prospect of tungsten copper tellurium contact will be more broad.

Tungsten Copper Tellurium (WCuTe) is a high-performance electrical contact material that combines the characteristics of tungsten, copper and tellurium. It has the following outstanding characteristics and applications:
