Copper/Tellurium Alloy Rod (Cu99.5/Te0.5)

Copper/Tellurium Alloy Rod (Cu99.5/Te0.5) combines copper’s exceptional electrical and thermal conductivity with tellurium’s ability to improve machinability, mechanical strength, and oxidation resistance. This composition maintains near-pure copper conductivity while significantly enhancing wear resistance and resistance to arc erosion, making it ideal for precision machining without sacrificing performance. In rod form, it offers uniform microstructure, dimensional stability, and excellent surface finish, enabling the production of high-performance electrical and electronic components. Primary applications include electrical connectors, semiconductor device mounts, and high-duty switchgear contacts, where both high conductivity and mechanical durability are critical. Technologies benefiting from this alloy include high-speed CNC-machined electrical parts, vacuum electronics bases, and precision current-carrying terminals in aerospace and power distribution systems. In research, it supports studies on microstructural control, phase stability, and the interplay between machinability and conductivity in high-purity copper systems. Its industrial value lies in delivering high-performance components with a strategic balance of conductivity, workability, and environmental resilience.
