In the rapidly evolving landscape of high-end manufacturing, the demand for high-purity materials has transitioned from a specialized requirement to a macro-industrial necessity. As a leading Custom Oxygen-free copper manufacturer, we recognize that the difference between standard electrolytic tough pitch (ETP) copper and Oxygen-Free High Conductivity (OFHC) copper often defines the success of billion-dollar infrastructure projects in aerospace, semiconductor fabrication, and clean energy.
Information Gain: Unlike standard copper, Oxygen-free copper (containing less than 0.001% oxygen) eliminates the risk of hydrogen embrittlement. In vacuum environments and cryogenic applications, this material property is non-negotiable for structural integrity and thermal management.
Our expertise at Kepai New Material focuses on the metallurgy of C10100 and C10200 alloys. By utilizing advanced vacuum induction melting (VIM) and continuous casting techniques, we ensure a grain structure that supports superior ductility and electrical conductivity exceeding 101% IACS (International Annealed Copper Standard).
Global net-zero targets are driving massive investments in Electric Vehicles (EVs) and renewable energy storage. Oxygen-free copper is the cornerstone of high-efficiency EV busbars and charging connectors, where thermal loss must be minimized to maximize range.
As we move toward higher data frequencies, signal attenuation becomes a critical failure point. High-purity OFC provides the low-impedance pathways required for next-generation telecommunications hardware and satellite communication systems.
The semiconductor industry’s move to sub-3nm nodes requires extreme vacuum environments. Oxygen-free copper’s low outgassing properties make it the preferred material for vacuum deposition chambers and high-purity gas delivery lines.
Procurement teams today face a dual challenge: ensuring material purity while navigating a volatile global supply chain. Our "Macro Solutions" approach integrates localized technical support with global compliance standards (ISO 9001, IATF 16949, RoHS, and REACH).
The roadmap for Oxygen-free copper manufacturing is shifting toward Ultra-High Purity (6N/7N) levels. At Kepai, our R&D focus includes:

Oxygen-Free Copper (OFC), such as C10100, is refined in a vacuum or inert atmosphere to reduce oxygen levels to below 10 ppm. Standard ETP copper contains oxygen that can react with hydrogen at high temperatures, causing "hydrogen embrittlement," which leads to material failure. OFC is immune to this effect.
Industries requiring high electrical and thermal conductivity combined with vacuum compatibility are primary users. This includes semiconductor manufacturing, high-end audio cabling, particle accelerators, and cryogenics.
Yes. As a global exporter, we comply with IATF 16949 for automotive quality, ISO 14001 for environmental management, and provide full RoHS/REACH documentation to ensure seamless localization and regulatory adherence in European and American markets.
Absolutely. We specialize in custom bars, foils, tubes, and rods. Our internal R&D and production system allow us to tailor the mechanical properties and dimensions to meet specific client blueprints.
