In the world of precision engineering, C14500 Tellurium Copper (CuTe) stands as the "Gold Standard" for components requiring a unique synergy of high electrical conductivity and superior machinability. While traditional pure copper offers excellent IACS values, its "gummy" nature makes high-speed CNC machining a nightmare.
As a leading high-tech enterprise with over 30+ patents and a 29,000 sqm facility, our expertise in C14500 is not just about manufacturing—it's about material science innovation that empowers global industries from EV charging to plasma cutting.

The core of C14500 is the addition of 0.4%-0.7% Tellurium. This creates fine telluride precipitates that act as "chip breakers," increasing the machinability rating to 85% compared to just 20% for pure copper.
Kepai’s R&D focuses on Oxygen-Free Tellurium Copper (OFT). By reducing oxygen content to under 10ppm, we eliminate hydrogen embrittlement risks, making the material ideal for vacuum electronics and high-temperature brazing.
As we look toward 2030, the demand for C145 is shifting toward 5G connectors and EV high-speed charging pins. Our roadmap includes grain-size refinement to improve fatigue resistance in vibration-heavy environments.
C14500 is no longer a niche material; it is a critical enabler for the green energy transition and advanced medical diagnostics.
Used in high-voltage connectors and DC fast-charging gun pins. The high conductivity (93-98% IACS) reduces heat generation during rapid charging.
Non-magnetic properties and bactericidal qualities make C145 perfect for MRI components and precision surgical electrodes.
Weight-to-conductivity efficiency is critical. C145 is used in generators and data transmission components where reliability is non-negotiable.
Plasma cutting nozzles and gas welding tips benefit from C145’s high thermal conductivity and arc resistance.
Kepai’s location in Sichuan leverages China’s robust industrial logistics network, allowing us to export to 30+ countries with shorter lead times than Western competitors.
Reliability is the cornerstone of our EEAT strategy. We don't just ship metal; we ship certified engineering solutions.
Every batch of C14500 is issued with a Mill Test Certificate (MTC) detailing exact chemical composition and physical properties.
Our technical team provides local support for Western engineering teams to optimize their designs for free-cutting copper alloys.
We offer silver, tin, and nickel plating services in-house to enhance corrosion resistance for harsh environment applications.
