In the realm of advanced metallurgy, C10200 Oxygen-Free (OF) Copper represents the pinnacle of purity and performance. Unlike standard electrolytic tough pitch (ETP) copper, C10200 is produced through a meticulous vacuum-melting process that reduces oxygen content to less than 0.001% (10 ppm). This technical specification is not merely a number; it is a critical requirement for applications where high thermal and electrical conductivity must coexist with hydrogen embrittlement resistance.
Sichuan Kepai New Materials Co., Ltd., established in May 2017, has emerged as a global leader in this niche. Our 29,000 square meter facility is dedicated to the R&D and production of specialized copper alloys, including C10200 and its derivatives like tellurium copper. By eliminating the residual oxides found in cheaper alternatives, we provide a material that maintains structural integrity during high-temperature brazing and welding operations.

Chinese factories like Kepai utilize fully integrated production lines, from raw material smelting and vacuum casting to precision drawing and extrusion. This ensures end-to-end quality control and traceability.
With a dedicated independent R&D team, we don't just supply standard alloys; we innovate. Our oxygen-free high conductivity tellurium copper (OFT) is a prime example of performance optimization.
Operating under ISO9001:2015, ISO14001:2015, and IATF 16949 standards, our products meet the rigorous safety and environmental requirements of the EU and North American markets.
The vast copper supply chain in China allows for competitive pricing without compromising the high-purity standards required for C10200 Oxygen-Free copper applications.
C10200 is essential for charging connectors and battery busbars. Its high conductivity minimizes energy loss, while its purity ensures durability against vibration and thermal cycling.
In high-vacuum environments, material outgassing is a risk. C10200’s low oxygen content makes it ideal for satellite components and high-frequency communication waveguides.
The antibacterial properties of high-purity copper, combined with its non-magnetic nature, make it vital for MRI equipment and advanced surgical tools.
The global demand for high-purity copper is projected to grow by 7% annually. Procurement leaders are shifting from "Transactional Buying" to "Strategic Partnerships." At Kepai, we provide:
A: Both are oxygen-free coppers. C10100 (OFE) is 99.99% pure with <5ppm oxygen, while C10200 (OF) is 99.95% pure with <10ppm oxygen. C10200 is often the cost-effective choice for most industrial and electrical applications that require high conductivity without the extreme cost of "electronic grade" purity.
A: Standard copper contains oxygen in the form of cuprous oxide. When heated during welding or brazing in a hydrogen-containing atmosphere, the hydrogen reacts with the oxygen to form steam, creating internal voids and cracks (hydrogen embrittlement). C10200 prevents this entirely.
A: Yes. Our production capabilities include tubes, rods, foils, and custom-extruded profiles. We specialize in precision tolerances to meet high-end manufacturing needs.
A: We utilize advanced spectral analysis and eddy current testing to provide a detailed data sheet for every shipment. Our expertise in Tellurium Copper also allows us to offer specialized alloys that combine the high conductivity of OF copper with the machinability required for complex components.
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.
Our company has passed ISO9001:2015, ISO14001:2015 and OHSAS 45001:2018. We focus on innovation and environmental protection, utilizing environmentally friendly materials to meet sustainable development goals.
