Explore our elite selection of high-conductivity, precision-engineered copper and copper-alloy products, tailored to withstand extreme thermal, physical, and electric demands.
In the realm of advanced engineering, electrical conductivity, and high-vacuum operations, the chemical purity of the underlying alloy dictates the performance threshold of the end system. UNS C10200 (Oxygen-Free Copper) represents the gold standard in high-purity copper, engineered with an elemental copper content of at least 99.95% and an extremely low oxygen percentage (typically maintained below 10 ppm or 0.001%).
For global industrial buyers, particularly those designing high-power electrical systems, electronic tube components, vacuum interrupters, high-speed rail systems, and nuclear energy equipment, selecting C10200 means choosing maximum reliability. With a nominal electrical conductivity of 100% to 101% IACS (International Annealed Copper Standard), it offers optimal pathing for electrical charge with minimal resistive heating.
| Alloy Grade | Cu % (Min) | O2 Content (Max) | Electrical Cond. (% IACS) | Thermal Cond. (W/m·K) | Primary Industrial Use Cases |
|---|---|---|---|---|---|
| UNS C10100 (OFE) | 99.99% | < 5 ppm | 101% | 391 | Semiconductor packaging, particle accelerators, aerospace, vacuum systems |
| UNS C10200 (OF) | 99.95% | < 10 ppm | 100% - 101% | 391 | High-power electrical busbars, coax cables, wave-guides, EV relays, lasers |
| UNS C11000 (ETP) | 99.90% | ~ 200 - 400 ppm | 100% | 388 | General electrical wires, roofing sheets, architectural panels, basic switches |
We are a pioneering high-tech enterprise dedicated to the research, development, custom manufacturing, and global distribution of specialized high-performance copper alloys.
The global demand for C10200 Oxygen-Free Copper is experiencing a compound annual growth rate (CAGR) driven by structural shifts in energy, telecommunications, and industrial automation. By understanding these macro-trends, procurement directors can secure supply chains that align with future standards.
Electric drivetrains and battery packs operate under extreme voltages and currents. Busbars and relays fabricated from C10200 ensure minimal energy dissipation, reducing localized heat buildup that could trigger thermal runaway in high-capacity lithium batteries.
High-frequency data transmission demands physical media with exceptionally smooth surface profiles and minimal internal resistivity. C10200 copper, with its high grain consistency, prevents signal dispersion in RF coaxial lines and microwave components.
In ultra-high vacuum (UHV) systems, common copper alloys leak trapped atmospheric gases—a process called outgassing. Because C10200 contains negligible volatile trace elements (like Zinc or Lead) and low oxygen, it is UHV-stable and prevents system de-pressurization.

Our production and management systems are fully certified by leading international certification bodies, ensuring that all copper alloy batches comply with RoHS, REACH, and ASTM standards.
From casting and smelting to physical verification and grain-level structural testing, our facility maintains a closed-loop quality guarantee chain.
Sourcing premium copper alloys is only half the battle. Delivering these alloys in formats that seamlessly integrate into your automated manufacturing lines requires custom solutions. At Sichuan Kepai, we assist engineering teams with comprehensive material selection guidelines and post-delivery fabrication support.
When fabricating waveguides or vacuum envelopes, brazing is standard. C10200's zero-oxygen content permits furnace brazing in dry hydrogen atmospheres without the risk of joint failure, yielding high-integrity joints and hermetic seals.
Pure copper is notoriously sticky and soft, making it difficult to machine without burr formation. We offer specialized cutting speed, rake angle, and coolant recommendations to optimize CNC turning of C10200.
Every shipment includes complete chemical composition analysis (ICP-OES / combustion method) and electrical resistivity charts, ensuring fully documented, stress-free compliance audits.
As high-frequency computing, aerospace electronics, and power grid infrastructures evolve, the standards for copper purity are rising. We are continually pushing metallurgical limits to prepare for these trends.
We are developing vacuum induction melting processes to lower oxygen levels to < 3 ppm. This will make our alloys suitable for cryogenic applications, quantum computer wiring, and deep-space communications.
We are researching graphene-embedded oxygen-free copper matrices. These hybrids are designed to yield up to 105% IACS conductivity while maintaining higher mechanical strength and wear resistance.
By utilizing renewable energy grids and advanced closed-loop copper scrap recycling systems, we aim to minimize the carbon footprint of our smelting and drawing operations.
