Cw114c (C14500 Tellurium Copper) has emerged as the cornerstone of precision engineering. Unlike standard copper, Cw114c introduces controlled amounts of tellurium to enhance machinability without compromising electrical conductivity. Our factory specializes in "Oxygen-Free" Cw114c, a variant that offers superior resistance to hydrogen embrittlement.
In 2024, procurement leaders in the EV and 5G sectors are prioritizing "Information Gain" in their supply chains. This means moving beyond raw material lists to data-driven alloy performance. Cw114c is increasingly sought for high-speed CNC machining where traditional copper fails to deliver the required surface finish.
Most alloys sacrifice conductivity for strength. Cw114c achieves a unique balance, maintaining 93-98% IACS while offering a machinability rating of 85. This makes it the ideal candidate for complex connectors and plasma cutting electrodes used in aerospace and medical devices.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength free cutting tellurium copper and other special copper alloys.
High-precision tellurium copper components for MRI and diagnostic devices. Copper's natural antimicrobial properties combined with Cw114c's machinability allow for complex surgical tool designs.
Electric vehicle charging pins and battery connectors require the extreme thermal and electrical performance of our custom alloys. Cw114c ensures minimal energy loss during rapid charging cycles.
From generator windings to high-speed data transmission pins, our oxygen-free tellurium copper withstands the rigors of flight and extreme temperature fluctuations.
We are currently optimizing our vacuum induction melting processes to reach 99.99% purity levels for oxygen-free variants, essential for the next generation of semiconductor manufacturing equipment.
Our R&D team is pioneering lead-free alternative alloys that match the machinability of C36000 and Cw114c, ensuring 100% compliance with future EU REACH and RoHS regulations.
Implementing AI-driven quality control across our 29,000 sqm facility to provide real-time batch traceability and performance analytics for our tier-1 global partners.
