Engineered to meet the stringent metallurgical tolerances, chemical purity specifications, and electrical conductivity requirements of Swiss manufacturers.
In the globalized industrial landscape, high-purity copper and specialized copper alloys represent the silent infrastructure powering advanced technology. Switzerland, celebrated for its unparalleled manufacturing precision, high-end horology, leading-edge medical technology (MedTech), and advanced scientific research (such as CERN), demands an uncompromising standard for raw materials. To maintain competitive excellence, Swiss enterprises cannot rely on standard commodity-grade metals; they require custom-engineered solutions with guaranteed performance metrics, strict dimensional tolerances, and complete transparency in the supply chain.
Switzerland’s economy is defined by high-value-added manufacturing. The Swiss market operates on a paradigm of quality, reliability, and precision over sheer volume. The requirements for pure copper in this market are highly localized and specialized across several key domains:
Key metrics highlighting our manufacturing scale, research initiatives, and commitment to global industrial partners.
The global copper market is undergoing a transition driven by two primary forces: the digital transition (incorporating 5G networks, microprocessors, and smart electric components) and the green transition (electric vehicles, wind/solar farms, and energy storage system relays). Consequently, global sourcing requirements have shifted from simple cost procurement to demanding long-term chemical, physical, and ecological transparency. Today, procurement officers in Europe, particularly in Switzerland, evaluate manufacturers on several core criteria:
As Western markets face capacity limits and escalating operational costs, China's transition to Factory 4.0 provides a combination of scale, agility, and technology. Modern Chinese metallurgical plants are no longer just volume suppliers; they are key centers of technical innovation. Sichuan Kepai New Material Co., Ltd. represents this paradigm change through:
Integrated Digital Smart Smelting: Utilizing closed-loop induction furnaces and automated real-time spectral analyzers, the casting process maintains absolute chemical purity, preventing oxide contamination at the source. This is particularly crucial for keeping oxygen content under 5 ppm in oxygen-free electronic grade copper.
Supply Chain Resilience: Positioned within Sichuan's industrial corridor, Kepai leverages local access to clean hydroelectric power, reducing the carbon footprint of the smelting process. Our integrated production—from casting, extrusion, drawing, to non-destructive testing—minimizes the risk of external delays, ensuring reliable delivery schedules directly to European distribution centers.
Established in 2017, Sichuan Kepai New Material Co., Ltd. is a high-tech enterprise integrating research and development, production, and sales. Located in the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108, our facility benefits from convenient transportation infrastructure, laying a solid foundation for rapid global distribution.
Kepai is dedicated to the business philosophy of "innovation-driven development, quality wins the market." We focus on providing strategic new materials, including special copper alloys such as tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper. Our advanced materials are widely utilized in new energy vehicles, 5G technology, plasma/laser cutting, and aerospace relays.
Our integrated manufacturing line features advanced machinery and testing laboratories to ensure all copper alloys comply with international standards.
Our quality management systems conform to strict international requirements, ensuring compliance and reliability for global engineering and high-end industrial projects.
Selecting the optimal copper alloy requires balancing conflicting physical requirements. While pure copper offers exceptional electrical conductivity, its high ductility poses challenges for complex, micro-precision machining. Conversely, highly machinable brasses often fall short in high-current applications due to reduced electrical conductivity.
For Swiss CNC micro-machining, C14500 Tellurium Copper provides a critical metallurgical solution. By introducing between 0.4% and 0.7% Tellurium, we produce a material with a machinability rating of 85% (relative to free-cutting brass), while preserving an electrical conductivity of at least 93% IACS. This combination allows for high cutting speeds, minimal tool wear, and precise thread details in watch screws, high-amperage electrical connectors, and laser cutting nozzles.
Our oxygen-free grades (such as C10100 and C10200) are manufactured via vacuum melting, maintaining oxygen content below 5 ppm (0.0005%). Eliminating copper oxides prevents hydrogen embrittlement when heating under reducing atmospheres, making this grade essential for scientific equipment, vacuum switches, and particle accelerators.
