High-performance specialty metals engineered to exceed the demanding standards of global industrial, automotive, and technological manufacturing.
A Leading Force in Advanced Metallurgy & Industrial Engineering since 2017
Established in 2017, Sichuan Kepai New Materials Co., Ltd. has developed into a state-recognized high-tech enterprise. Our core focus spans research, development, custom synthesis, and large-scale manufacturing of high-precision copper and specialized copper-alloy strips, rods, and profiles. Currently, our manufacturing and metallurgical facilities occupy approximately 9,000 square meters, complemented by a 1,000 square meter research and administrative center. By specializing in strategic emerging new materials—a key vertical aligned with national advanced manufacturing initiatives—Kepai provides a reliable industrial supply chain for high-conductivity oxygen-free copper, silver copper, dispersion-strengthened copper, and specialty alloys like tellurium and beryllium copper. Our primary application areas cover ultra-demanding fields, including new energy electric vehicles (NEVs), 5G communication infrastructure, high-power industrial laser systems, and high-frequency battery relays.
Navigating Complexity in Modern Advanced Electronic Supply Chains
In the current macroeconomic landscape, electronic systems are driving towards miniaturization, high current densities, and extreme thermal loads. Design engineers and global procurement officers are faced with the challenge of selecting copper strips that maintain electrical conductivity (>97% IACS) while offering the high mechanical strength necessary to survive high-speed stamping operations without fracture.
Modern progression press stamping demands thickness tolerances down to ±0.005mm. Any deviations introduce assembly variances in connectors and switchgear, leading to high rejection rates.
Electric vehicle battery management units and high-current relays experience severe thermal cycling. Only pure, oxygen-free copper and thermal-resistant tellurium copper alloys prevent thermal runaway.
Hard-to-machine alloys accelerate tool wear. Sichuan Kepai resolves this issue by engineering micro-alloyed, easy-to-machine sulfur and tellurium coppers that extend stamping tool lifespans by up to 300%.

Certified performance and international standards adherence to ensure supply chain reliability
Full manufacturing tracking from continuous melting and extrusion to precision physical and chemical analysis
Engineered high-performance materials optimized for next-generation technological infrastructure
The electrical infrastructure of electric vehicles relies on stable, low-resistance connections. Sichuan Kepai manufactures specialized, high-conductivity, oxygen-free copper strip profiles that serve as the backbone for battery busbars, charging connectors, and power distribution units. These products ensure minimal I²R resistive heating, reducing energy loss and supporting fast-charging capabilities.
High-frequency data networks require stable signal integrity. Our ultra-thin, high-precision copper strips are utilized in 5G transceiver stations, coaxial line connectors, and RF shielding components. With high micro-structural purity, they minimize signal attenuation and maintain structural integrity under outdoor operating conditions.
High thermal load processes, such as plasma and laser cutting, require durable consumables. Sichuan Kepai's tellurium-copper (C14500) and sulfur-copper alloys are engineered for manufacturing plasma electrodes and cutting tips. Their electrical conductivity, combined with excellent machinability, allows for tight machining tolerances and extended nozzle lifetimes.
Pushing the performance limits of industrial copper alloys for future applications
Developing high-strength, high-conductivity (HSHC) copper matrices by doping trace levels of zirconium, chromium, and phosphorus. This approach optimizes the trade-off between mechanical strength (yield stress > 550 MPa) and electrical performance (>85% IACS), creating reliable materials for heavy-duty automotive relays.
Scaling our high-precision thin strip production lines to deliver foil thicknesses down to 0.05mm. This micro-gauge strip material is designed for sub-miniature consumer electronic relays, smart grids, and lightweight battery tabs.
Phasing out traditional leaded brasses by optimizing bismuth and sulfur coppers. This path guarantees compliance with global RoHS and REACH directives while providing the high-speed machinability required by precision CNC manufacturing.
Meeting stringent quality and supply chain standards across international borders
Exporting high-precision materials to global markets requires strict compliance and logistics management. Sichuan Kepai maintains an international export framework that covers all quality control and compliance milestones:
Every shipment is tested to verify that heavy metal content is within RoHS boundaries, making our products safe for European and American markets.
Our ERP system tracks raw materials from initial smelting to final packaging. Material Test Reports (MTRs) detailing chemical analysis and mechanical values accompany every shipment.
To protect copper's finish during sea transit, we package our coils and rods with vacuum-sealed desiccants and VCI (Volatile Corrosion Inhibitor) wraps.
Insights from our engineering team on copper alloy performance and applications
Expanded specialty alloy options for diverse industrial manufacturing applications
Looking ahead, Sichuan Kepai New Materials Co., Ltd. will continue to uphold its original intention, with even greater enthusiasm and determination, to engage in research and application in the field of new materials, contributing to the development of the new copper alloy materials industry in China and globally.
