Why choose our oxygen-free high-conductivity tellurium copper?
In fields such as 5G communications and semiconductor packaging, conventional copper materials are prone to hydrogen embrittlement due to high oxygen content, leading to device failure. Our oxygen-free high-conductivity tellurium copper, with an oxygen content of ≤0.003% and micro-alloyed with tellurium, eliminates the risk of hydrogen embrittlement while maintaining industry-leading electrical conductivity.
