In the evolving landscape of high-performance electronics, semiconductor manufacturing, and electric vehicle (EV) infrastructure, the demand for high-purity materials has never been more critical. Oxygen-Free Copper (OFC), specifically grades like C10100 (99.99% purity) and C10200 (99.95% purity), represents the pinnacle of metallurgical excellence. At Sichuan Kepai New Materials Co., Ltd., we provide "Information Gain" to the market by not just supplying materials, but by engineering solutions that prevent hydrogen embrittlement and maximize electrical IACS conductivity.
Traditional ETP (Electrolytic Tough Pitch) copper contains a small amount of oxygen in the form of cuprous oxide. While sufficient for general electrical work, it fails in high-temperature vacuum processes where oxygen reacts with hydrogen to cause internal fractures. Our Oxygen-Free Copper Rods are processed under strict vacuum induction melting (VIM) conditions, ensuring an oxygen content of less than 5 ppm. This results in superior thermal stability and a grain structure optimized for ultra-fine wire drawing and complex machining.
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.
Advancing from 4N (99.99%) to 5N (99.999%) purity levels to support the next generation of cryogenic cabling and quantum computing interconnects.
Integrating trace amounts of Tellurium or Zirconium into Oxygen-Free bases to achieve "Free-Cutting" properties without sacrificing conductivity—a breakthrough for automated CNC production.
Implementing 100% closed-loop recycling and hydrogen-based reduction processes to minimize the carbon footprint of copper smelting, aligning with global ESG mandates.
As a leading Oxygen Free Copper Rod Company, Sichuan Kepai understands that global enterprises do not just buy copper; they buy operational uptime and product reliability. Our macro solutions span across diverse sectors:
Our OFC rods are the primary feedstock for high-current charging connectors and motor windings, reducing heat generation by 15% compared to standard copper.
Providing oxygen-free tellurium copper for plasma cutting electrodes and generator components where weight-to-conductivity ratios are paramount.
Essential for MRI magnets and high-frequency surgical tools, our materials ensure interference-free performance in life-critical environments.
Sichuan Kepai leverages Industry 4.0 principles to ensure efficiency and quality. Our facility in Sichuan uses real-time monitoring of melting temperatures and gas composition to guarantee every batch of Oxygen-Free Copper meets the highest international standards.
