Established in May 2017, Sichuan Kepai New Materials Co., Ltd. has emerged as a high-tech vanguard in the R&D and manufacturing of specialized copper alloys. Our facility, spanning 29,000 square meters, is a nexus of technological innovation where we produce high-conductivity, high-strength free-cutting tellurium copper and oxygen-free copper (OFC) that meet the most stringent industrial requirements.
As a premier Oxygen Free Copper Manufacturer & Exporter, we provide more than just raw materials; we deliver "Information Gain" and technical expertise that empower our clients in the semiconductor, aerospace, and EV sectors. Our oxygen-free products are characterized by a purity level of 99.99%, ensuring resilience against hydrogen embrittlement and offering the highest thermal and electrical conductivity possible for metallic copper.

In traditional ETP (Electrolytic Tough Pitch) copper, residual oxygen (usually 200-600 ppm) can lead to "hydrogen embrittlement" when heated in a reducing atmosphere. Our manufacturing process utilizes vacuum melting and continuous up-casting to reduce oxygen content to below 5-10 ppm. This metallurgical precision is critical for applications involving high-frequency data transmission and high-power vacuum electronics.
99.99% pure copper with less than 0.0005% oxygen content. The gold standard for particle accelerators and high-end audio cabling.
High conductivity copper with 99.95% purity, offering excellent joinability and resistance to hydrogen embrittlement.
Our proprietary blend combining the conductivity of OFC with the superior machinability of Tellurium copper.
The industry roadmap for 2025-2030 points toward the miniaturization of power electronics. This requires copper alloys that can handle higher current densities without thermal failure. Kepai is currently researching "Nano-Structured OFC" to enhance grain boundary strength without sacrificing the IACS (International Annealed Copper Standard) conductivity rating.
Located in Sichuan, we leverage the "Belt and Road" inland logistics and major port connections to ensure lead times are reduced by 20-30% compared to traditional regional suppliers.
From raw material smelting to precision machining (foil, tube, rod), our vertically integrated factory minimizes quality variance and cost leakage.
Full adherence to ISO 9001:2015, ISO 14001:2015, and OHSAS 45001:2018. We ensure our products meet REACH and RoHS standards for the European and North American markets.
Our OFC busbars and connectors are vital for battery management systems (BMS), where minimal electrical resistance is required to prevent overheating during rapid charging.
OFC wires and data transmission parts in satellites require the highest reliability. Our oxygen-free alloys maintain structural integrity in vacuum environments.
Used in MRI machines and high-precision diagnostic tools where non-magnetic and high-conductivity properties are non-negotiable.
High-performance copper alloys with superior corrosion resistance for seawater-facing sensors and power transmission modules.
Unlike standard manufacturers, Kepai invests 8% of annual revenue into alloy innovation. Our R&D team has developed a new type of highly conductive oxygen-free tellurium copper that outperforms traditional alloys in both conductivity and machinability.
Mature production technology and complete system control from casting to finished product.
We participate in the formulation of industry standards, ensuring our clients always stay ahead of regulatory changes.
Focusing on environmentally friendly and free-cutting copper alloys to reduce the ecological footprint of industrial manufacturing.
A: C11000 (ETP) contains oxygen, making it susceptible to embrittlement during welding. C10100 (OFE) is 99.99% pure and oxygen-free, offering better weldability and higher conductivity.
A: Yes, as a custom manufacturer, we provide a wide range of sizes and shapes, including foil, tubes, and rods, tailored to your specific engineering drawings.
A: We use vacuum induction melting and real-time spectral analysis to ensure the chemical composition meets 99.99% purity and oxygen levels remain under 10ppm.
A: Standard orders usually ship within 2-4 weeks. Our logistics team handles all customs and compliance documentation for a seamless delivery process.
Industrial Status: Oxygen-free copper remains a "strategic material" in the global electronics supply chain. With the rise of 5G infrastructure, the demand for OFC foils used in high-frequency PCBs has surged by 40% annually. Our China-based factory leverages local lithium and copper mining clusters in the Sichuan-Tibet region to maintain a stable cost structure despite global market fluctuations.
Compliance & Support: Beyond manufacturing, we provide localized support for our partners in Europe, Southeast Asia, and North America. This includes technical data sheets (TDS), safety data sheets (SDS), and metallurgical consulting for complex aerospace engineering projects. Our goal is to ensure that every kg of copper we export contributes to a higher efficiency and longer lifecycle for the end product.
