Engineered for absolute conductivity and precise structural alignment under critical industrial conditions.
How Sichuan Kepai New Material Co., Ltd. leads scientific formulation and strict industrial production.
Established in 2017, Sichuan Kepai New Material Co., Ltd. stands as a premier high-tech enterprise dedicated to the R&D, processing, and distribution of advanced metallurgical solutions. Our state-of-the-art production facility, located in the Western Area of the Sichuan Guanghan Industrial Development Zone adjacent to National Highway 108, covers approximately 9,000 square meters alongside an office infrastructure of 1,000 square meters.
Strategically aligned with China's emerging national new materials initiatives, Kepai integrates advanced induction smelting, oxygen elimination processes, and cold processing methods. We focus on producing special copper alloys including tellurium copper, high-conductivity oxygen-free copper (OFC), silver copper, and dispersion copper. Driven by the philosophy "innovation-driven development, quality wins the market," our engineers develop copper alloys that combine high electrical and thermal conductivity with high-strength performance and easy machinability.
As the demand for energy-dense, high-efficiency, and low-impedance electrical interconnects rises globally, the purity of copper has become a key engineering metric. Our oxygen-free high-conductivity (OFHC) copper contains less than 10 ppm of oxygen, offering excellent electrical conductivity (minimum 100% IACS), immunity to hydrogen embrittlement, and superior vacuum performance.
Deep technological evolution driving demands in modern industrial subsystems.
Modern electrical grids, new energy vehicles, and high-frequency communication electronics depend heavily on the quality of their conductive core materials. Impurities in standard copper alloys (like oxygen, sulfur, and lead) can scatter electrons, creating thermal hotspots and decreasing system efficiency. Oxygen-free copper (ASTM C10100 & C10200) prevents these performance losses, making it essential for high-performance applications.
| Alloy Grade | UNS Number | Min. Conductivity (% IACS) | Max. Oxygen Content (ppm) | Primary Industrial Use Cases |
|---|---|---|---|---|
| High Purity OFHC | C10100 | 101% | < 5 ppm | Cryogenics, vacuum electronics, semiconductor tooling |
| Oxygen-Free (OF) | C10200 | 100% | < 10 ppm | Busbars, EV power cables, high-speed telecom guides |
| Tellurium Copper | C14500 | 93% - 98% | Controlled | Plasma cutting nozzles, smart power meters, EV connectors |
| Chromium Zirconium | C18150 | 80% | N/A | Resistance welding electrodes, EDM tooling |
China's industrial evolution has transitioned from high-volume manufacturing to precision engineering and metallurgical innovation. By adopting automation, closed-loop vertical smelting, and real-time spectrophotometric quality analysis, Chinese manufacturers like Sichuan Kepai ensure consistent product performance. This structural improvement guarantees secure supply chains and steady price-to-performance ratios for global OEMs.
