In the era of rapid electrification and high-frequency data transmission, the choice of conductor material determines the ceiling of system efficiency. Sichuan Kepai New Material Co., Ltd., established in 2017, has emerged as a cornerstone in the global supply chain, specializing in the R&D and mass production of Oxygen-Free Tellurium Copper (OFTC).
Unlike standard copper, our oxygen-free process eliminates the risk of hydrogen embrittlement. This results in superior electrical conductivity (>93% IACS) and exceptional thermal management capabilities, essential for high-power semiconductor cooling.
By precisely introducing tellurium, we achieve a machinability rating of 85% compared to free-cutting brass. This allows for complex geometric shapes in connectors and plasma tips while maintaining high-end conductivity.
With 30+ patents and ISO 9001:2015, ISO 14001:2015, and IATF 16949 certifications, Kepai ensures that every batch meets rigorous aerospace and automotive standards for reliability and sustainability.
Based in Sichuan, China, our 29,000 m² state-of-the-art facility is dedicated to breaking the boundaries of traditional metallurgy. We focus on information gain through technical transparency, providing our clients with deep metallurgical analysis and performance data that competitors simply don't offer.
Our R&D team doesn't just produce alloys; they engineer solutions for plasma cutting electrodes, new energy vehicle connectors, and high-speed data transmission pins. We leverage an independent production system that allows for rapid prototyping and bespoke alloy tuning for global OEMs.
Sichuan Kepai benefits from China's integrated industrial ecosystem. Our proximity to high-purity raw copper sources and advanced logistics hubs allows us to offer short lead times and cost-efficiency without compromising the material integrity required by EU and US standards.
We provide comprehensive localization services, including ROHS, REACH, and custom compliance reporting for diverse markets. Our technical support team works directly with your engineers to ensure tellurium copper integration meets local safety and performance regulations.
The industry is shifting toward Lead-Free Copper and Energy-Efficient alloys. Kepai is at the forefront of this trend, developing new tellurium-based alloys that replace leaded brass, catering to the strict environmental mandates of the medical and water industries.
High-conductivity connectors and charging pins require materials that handle high currents with minimal heat generation. Our OFTC is the preferred choice for EV thermal management systems.
Weight-to-conductivity ratios are critical. Our tellurium copper alloys provide the structural strength and electrical reliability needed for generators and data modules in harsh environments.
Copper's inherent antimicrobial properties combined with our free-cutting tellurium technology allow for the creation of intricate, safe components for high-tech medical devices.
Resistance to seawater corrosion and biological fouling makes our special copper alloys indispensable for subsea sensors and connectors.
We operate a proprietary R&D laboratory that focuses on "Atomic-level alloying," ensuring tellurium is distributed evenly throughout the copper matrix. This prevents "hard spots" that can damage precision Swiss-turn machining tools.
Our commitment to quality is validated by ISO 9001, ISO 14001, and OHSAS 18001. We maintain full traceability for every ingot and rod, providing MTRs (Material Test Reports) that document chemistry and physical properties.
While C14500 is a standard tellurium copper, the "Oxygen-Free" variant (OFTC) provides even higher conductivity and greater resistance to hydrogen embrittlement, making it safer for brazing and welding in vacuum environments.
We control the tellurium content within strict tolerances. This ensures that the material forms small, brittle chips during machining, which reduces tool wear and prevents the "long stringer" chip issues associated with pure copper.
Yes. Our R&D team specializes in tailoring mechanical properties (hardness, tensile strength) and conductivity levels to meet specific client requirements, often developing unique batch-specific solutions.
Thanks to our optimized supply chain in China and strategic partnerships with global shipping lines, we typically offer lead times 20-30% faster than the industry average for custom extrusions.
