Engineered for high-conductivity and superior machinability in European industrial standards.
France has positioned itself as a global leader in high-tech manufacturing, specifically within the Aerospace (Toulouse cluster), Nuclear Energy, and the rapidly expanding Electric Vehicle (EV) Gigafactories in the Hauts-de-France region. For these industries, standard copper often falls short due to machinability constraints. This is where Tellurium Copper (CuTe), specifically the C14500 grade, becomes a critical "Information Gain" component for French procurement officers.
French engineering firms, such as those in the Vallée de la Chimie near Lyon or the maritime hubs in Nantes, require materials that comply strictly with REACH and RoHS regulations while maintaining high thermal stability. Our Tellurium Copper production process involves precision alloying that ensures zero hydrogen embrittlement—a vital factor for the French nuclear sector (EDF) and high-vacuum applications in research laboratories like CERN.
The global supply chain for Tellurium Copper is tightening. French manufacturers are shifting from "Just-in-Time" to "Just-in-Case" procurement, seeking reliable exporters who can provide:
Advancing the boundaries of copper alloy science for the next generation of connectivity.
IACS Conductivity in OFT Grades
Machinability Rating
Innovation Patents
Global Industrial Partners
The technical roadmap for Tellurium Copper is moving toward Oxygen-Free Tellurium (OFT). Standard C14500 can sometimes suffer from internal oxidation during welding or brazing. Our R&D team has developed a specialized melting process that maintains tellurium's free-cutting benefits while eliminating oxygen. This is particularly relevant for the French defense and aerospace sectors, where material failure is not an option.
With France's commitment to ban petrol cars by 2035, Tellurium Copper is essential for fast-charging connectors and power distribution units (PDUs) where low contact resistance is mandatory.
In Toulouse-based aircraft manufacturing, our alloys are used in high-reliability sensors and connectors that must withstand extreme temperature fluctuations while maintaining electrical integrity.
French metal fabrication shops utilize our Tellurium Copper for plasma torch nozzles due to its high melting point and excellent thermal conductivity, extending tip life by up to 40%.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech pioneer specializing in R&D, production, and sales of high-conductivity tellurium copper. Covering 29,000 square meters, our facility is a beacon of modern metallurgy.
Our commitment to Information Gain is reflected in our 30+ patents and our participation in setting national industry standards. For our French clients, this means every rod, sheet, or wire comes with a pedigree of scientific excellence.

Our engineers provide deep-dive technical sessions via Zoom/Teams for French engineering firms to help optimize alloy selection for specific CNC machining parameters, reducing cycle times and tool wear.
Expert insights into Tellurium Copper procurement and applications.
C14500 Tellurium Copper has a machinability rating of 85%, compared to only 20% for pure copper. The addition of tellurium creates small, brittle chips that break easily, allowing for significantly higher CNC spindle speeds and longer tool life without sacrificing high electrical conductivity (typically >93% IACS).
Yes, our alloys are manufactured to meet or exceed international standards including ASTM B301 and European EN standards. We provide EN 10204 3.1 certification with every batch to ensure total compliance for French industrial projects.
For applications such as vacuum electronics or brazing, we offer Oxygen-Free Tellurium Copper (OFT). By strictly controlling the oxygen content to below 10ppm during the melting process, we eliminate the risk of embrittlement when the material is exposed to reducing atmospheres at high temperatures.
Standard rods and plates are often in stock for immediate shipment. Custom profiles or large-scale industrial orders typically have a production lead time of 2-4 weeks, with sea freight to France taking approximately 30-35 days or air freight taking 5-7 days.
