Tellurium copper is an alloy material made by adding trace tellurium element on the basis of pure copper. The addition of tellurium significantly improves the cutting performance of the material, while maintaining the excellent electrical and thermal conductivity of copper. Copper telluride has a conductivity of over 90% IACS and a thermal conductivity of over 350W/m·K, which makes it an ideal material for the manufacture of precision electronic components.

Tellurium copper is also superior in processing properties. Its cutting performance index can reach more than 80%, which is much higher than that of ordinary copper alloys. This feature greatly improves the production efficiency and reduces the processing cost. In addition, tellurium copper also has good welding properties and surface treatment properties, which is convenient for subsequent processing.

The typical chemical composition of tellurium copper includes: copper content ≥99.5%, tellurium content 0.4-0.7%, and the rest is trace elements. This precise composition ratio ensures the stability and consistency of material properties.

In terms of physical properties, the density of tellurium copper is 8.9g/cm³, the melting point is 1083℃, and the coefficient of thermal expansion is 17.0×10⁻⁶/℃. These parameters determine its stability and reliability in high temperature environments. The mechanical property parameters show that the yield strength of tellurium copper is ≥200MPa and the elongation is ≥15%, which ensures the safety and durability of the material during use.

In the electrical and electronic industry, tellurium copper is widely used in connectors, relays, switches and other key components. Its excellent electrical conductivity and processing properties ensure the reliability and stability of electronic equipment.

In the automotive industry, tellurium copper is used to make components such as sensors, terminals, and fuses. Its high temperature resistance and corrosion resistance meet the requirements of the harsh operating environment of the automobile.

In the aerospace sector, tellurium copper's high strength and highly conductive properties make it the material of choice for the manufacture of precision instruments and electronic devices. Its reliability and durability guarantee the safe operation of aerospace equipment.
