China Suppliers Factory: High Conductivity Oxygen-Free Tellurium Copper for New Energy and Precision Electronics

In the rapidly evolving sectors of new energy vehicles and precision electronics, traditional tellurium copper materials have struggled to balance conductivity and processing performance. Research shows that the conductivity of standard tellurium copper reaches only 80-90% of oxygen-free copper, which limits its use in critical applications like high-voltage connectors and precision electromagnetic components. As the global new energy industry demands materials that excel in both conductivity and ease of processing, innovation is crucial. As leading suppliers in China, our factory is dedicated to developing advanced materials that meet these pressing needs, ensuring that manufacturers can rely on high-quality solutions for their operational challenges

Product Detail

Core of Technological Breakthrough

In response to the demands of such manufacturers, Sichuan Kepai innovated the production process and developed an oxygen-free high-conductivity tellurium copper with completely independent intellectual property rights, which has extremely low oxygen content, extremely high conductivity, easy machinability, and excellent resistance to fusion welding.

Oxygen content ≤ 5ppm (up to TU00/C10100 oxygen-free copper standard)

Conductivity ≥ 95% IACS (more than 20% higher than traditional copper tellurium)

Cutting performance index is increased to more than 90%.
