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.
The oxygen content level is extremely low (less than 10ppm or ≤0.003%), which is equivalent to the high purity standards of TU0 / C10200 copper.
By maintaining an oxygen content of ≤0.003%, our copper eliminates the risk of hydrogen embrittlement, a common cause of failure in conventional copper used in high-temperature 5G and semiconductor applications.
It features an electrical conductivity of ≥97% IACS and a thermal conductivity coefficient of 415 W/(m·K), ensuring excellent energy transmission and heat dissipation.
Yes, it features an extremely easy-cutting, non-stick tool quality, along with excellent capacities for both cold working and hot forming.
It is primarily used in precision hardware processing, plasma/laser welding, medium-to-low voltage switchgear, and new energy automotive components like charging guns and battery poles.
