Tellurium copper core characteristics

• High electrical and thermal conductivity: tellurium copper conductivity can reach more than 90% IACS, close to the level of pure copper, while having excellent heat dissipation capacity, suitable for high-load electrical components.
• Excellent machining performance: The addition of tellurium significantly improves cutting performance, machining complex precision parts and reducing tool wear.
• Resistance to softening and high temperature: the strength is still maintained in high temperature environment, and the long-term working temperature can reach 200°C or more.
• Corrosion resistance and oxidation resistance: The surface forms a dense oxide film, resistant to moisture, acid and alkali environment corrosion.

Main application field

Electronic connector: 5G base station, new energy vehicle battery connection piece

Switch components: relay, circuit breaker contact

Welding electrode: resistance welding head, spot welding electrode

Heat conduction element: radiator substrate, semiconductor package

Why copper tellurium?

Compared to ordinary copper alloys, tellurium copper can reduce machining time by more than 30% in precision machining scenarios, while extending part life by 2-3 times. Its balanced cost performance meets the development trend of lightweight and efficient industrial equipment.
