Applications of OFT copper:
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.
Frequently Asked Questions (FAQ)
What is Oxygen-Free High-Conductivity Tellurium Copper?
It is an advanced copper alloy micro-alloyed with tellurium, featuring exceptionally low oxygen levels (under 10ppm). This combination offers high electrical and thermal conductivity alongside excellent machinability and resistance to hydrogen embrittlement.
How does this alloy prevent hydrogen embrittlement?
By maintaining an oxygen content level lower than 10ppm (equivalent to TU0/C10200 standards), the alloy avoids the formation of cuprous oxide. This eliminates the chemical reaction with hydrogen that causes internal cracking and embrittlement during high-temperature processing.
What are the electrical conductivity specs of OFT copper?
Our oxygen-free high-conductivity tellurium copper achieves an electrical conductivity rating of ≥97% IACS, ensuring efficient power and signal transmission in demanding electronic systems.
Is OFT copper suitable for high-speed machining?
Yes, it features extremely easy cutting and non-stick tool properties. This significantly reduces tool wear and allows for high-speed, high-precision manufacturing of complex components.
In which industries is this material primarily used?
It is widely applied in 5G communications, semiconductor packaging, automotive terminals, high-current charging gun connectors, lithium-ion battery poles, and plasma or laser cutting nozzles.
