Kepai Oxygen free high conductivity tellurium copper
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)
The cutting performance index is increased to more than 90%.
Product Advantage Matrix
OFT series oxygen-free and high-conductivity tellurium copper perfectly balances four core properties:
Conductive revolution: the conductivity exceeds 97% IACS (Kopai OFT-1) and reaches the oxygen-free copper level
Processing innovation: Maintain the excellent machinability of tellurium copper, and increase processing efficiency by 40%
Stable quality: The whole production process can be traced and strictly controlled, and the performance of the finished product is stable
Cost optimization: 25% reduction in overall cost compared with oxygen-free copper materials
Application Value Map
The material excels in key areas:
New energy field: the conductivity efficiency of battery pole connectors is increased by 22%
Power equipment: DC relay contacts more than 30 times without sticking
Precision machining: the qualified rate of plasma nozzle processing is increased to 99.3%
