Explore our core selection of certified strategic copper alloys, refined for extreme precision applications.
Beryllium Copper Alloy 25 (UNS C17200) represents the gold standard in premium precipitation-hardening copper alloy technology. Structurally comprising 1.8% to 2.0% beryllium with micro-alloy additions of cobalt and nickel, this compound undergoes rigorous heat treatment regimes to achieve ultimate tensile strengths exceeding 1400 MPa, with hardness levels approaching Rockwell C45. Consequently, design engineers specify C17200 for systems that demand high durability alongside high electrical and thermal conductivity.
Under current global industrial shifts, the procurement of high-performance conductive metals faces tightening parameters. Clean energy mandates, electric vehicle (EV) growth, and telecommunication expansions require high-reliability components. Beryllium Copper 25 provides reliable performance in high-cycle connector interfaces, aerospace sensor housings, oilfield exploration equipment, and automotive relay mechanisms.
Industrial sourcing teams prioritize supplier credentials. Procurement criteria have shifted from basic cost concerns to a focus on structural properties. Suppliers must demonstrate chemical consistency, uniform precipitate dispersion, and compliance with ASTM B194, ASTM B196, and AMS 4533 standards. Sichuan Kepai New Material Co., Ltd. addresses these requirements with raw material testing, precise melt control, and fully documented manufacturing traceabilities.
Environmental stewardship and occupational safety are key elements in modern supply chain management. Because processing raw beryllium involves occupational health controls, procurement teams prefer vertically integrated companies that manage refining, casting, and safety measures in controlled industrial facilities. Kepai's modern facility utilizes filtration systems and dust controls, aligning with global ESG standards.

Sichuan Kepai New Materials Co., Ltd., established in 2017, is a high-tech enterprise integrating research and development, production, and sales. Currently, the factory covers an area of approximately 9,000 square meters, with an office space of about 1,000 square meters. The company primarily engages in the production of strategic emerging new materials, including special copper alloys such as tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper, while also focusing on the research and development of high-conductivity, easy-to-machine, high-strength copper alloys.
Our production facility is located in the western area of the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108. This location offers convenient logistics connections to major shipping hubs, facilitating reliable distribution of raw materials and finished products to our international clientele.
Kepai operates on the business philosophy of "innovation-driven development, quality wins the market." Our research and development efforts are supported by a team of metallurgists and process engineers, enabling us to supply high-end copper materials for demanding global applications.
How modern technology, logistics planning, and manufacturing standards ensure stable, high-quality copper alloy supply chains.
Sichuan Kepai's manufacturing processes incorporate automated thermal control systems and precise furnace monitoring. Our melting operations are monitored by real-time alloy scanners, ensuring that the beryllium concentration in Alloy 25 remains within the strict 1.8% - 2.0% range. Minimizing compositional variation helps prevent structural irregularities during downstream aging heat treatments.
Following chemical formulation, our material is processed through high-tonnage hot extrusion presses and automated multi-stage cold drawing benches. This combination helps refine the grain structure, aligning with ASTM fine-grain specifications. Cold drawing increases the tensile strength of the copper matrix, preparing the material for final custom tempering operations.
In a complex global market, Kepai maintains reliable lead times by managing a robust raw material inventory and optimizing transport logistics. By coupling local raw material sourcing with direct access to major domestic transport routes and international ports, we ensure stable delivery for critical operations worldwide.
