In the rapidly evolving landscape of 21st-century industry, Oxygen-Free Copper (OFC) has emerged as the cornerstone of high-performance electrical and thermal systems. As a premier Oxygen Free Copper Factory, we understand that global enterprises are no longer just seeking raw materials; they are seeking reliability, conductivity, and purity levels that exceed 99.99%.
From the high-frequency signal transmission required in 5G telecommunications to the extreme cooling demands of particle accelerators, OFC (specifically C10100 and C10200 grades) provides the thermal conductivity and resistance to hydrogen embrittlement that standard ETP (Electrolytic Tough Pitch) copper cannot match. Our export operations cater to a diverse range of procurement needs, ensuring that every batch of material meets the rigorous ASTM B170 and BS EN 1977 standards.
We provide integrated solutions for the New Energy Vehicle (NEV) sector, focusing on high-efficiency busbars and charging connectors that utilize our proprietary tellurium-copper alloys to prevent overheating during rapid charging cycles.
Our R&D is currently focused on Micro-Alloying Technologies. By introducing trace elements like Tellurium or Sulfur into an oxygen-free matrix, we achieve "Free-Cutting" properties without sacrificing the high conductivity essential for precision electrical components.
The "Green Industrial Revolution" demands sustainable supply chains. Our factory is transitioning to 100% circular economy models, utilizing advanced refining techniques to ensure recycled copper reaches OFC purity levels with 40% less carbon footprint.
Focus on high conductivity and high strength free cutting tellurium copper and other copper alloys
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.
Passed ISO9001:2015, ISO14001:2015 and OHSAS 45001:2018.
Independent R&D team and complete production system for high-end copper alloys.
High share of domestic market and exported to overseas clients with high reputation.
Bactericidal and anti-inflammatory effects of high-purity copper alloys in diagnostic devices.
Best choice for system efficiency, battery terminals, and high-voltage distribution units.
Ideal for generators, data transmission parts, and radiation-shielded electronics.
Exceptional resistance to seawater corrosion and marine biological fouling.
In the world of high-value alloy exports, localized technical support is the bridge between a supplier and a partner. At Kepai, we provide on-site metallurgical consulting and localized compliance documentation for the EU (RoHS/REACH), North America (ASTM), and Asia (JIS) markets.
Our commitment to E-E-A-T principles means we don't just ship products; we share expertise. Every shipment is accompanied by a comprehensive Mill Test Certificate (MTC) detailing the chemical composition and physical properties, ensuring 100% traceability from raw ingot to finished rod, tube, or foil.
Located in Sichuan, we leverage the 'Belt and Road' rail networks and major maritime ports to provide "Just-In-Time" delivery to over 30 countries, reducing lead times for critical infrastructure projects.
Equipped with a complete production system and mature technology in special copper alloys.
Developing new types of highly conductive oxygen-free tellurium copper for high-end markets.
ISO9001, ISO14001, and OHSAS 45001 reflect our international operational standards.
Focusing on environmental protection through eco-friendly and free-cutting copper alloys.
C10100 (OFE - Oxygen-Free Electronic) is 99.99% pure with a maximum oxygen content of 0.0005%, while C10200 (OF - Oxygen-Free) is 99.95% pure. C10100 is preferred for high-vacuum applications where even minute impurities can cause gassing issues.
By precisely controlling the addition of 0.4% to 0.7% Tellurium, we create fine dispersed telluride particles that act as chip breakers during machining, significantly improving tool life and production speed.
Yes, our vertical integration allows us to offer custom thicknesses for foils down to 0.01mm and tubes with variable wall thicknesses to meet specific aerospace or medical design requirements.
Absolutely. All our high-conductivity alloys are tested by third-party labs to ensure they are free of restricted substances, making them safe for global distribution and sensitive electronic applications.
Standard stock items can be shipped within 7-10 days. Custom alloy formulations or specific dimensions typically have a lead time of 3-5 weeks depending on the order volume and complexity.
