High-precision metallurgical materials engineered to meet the stringent demands of Brazilian manufacturers and tier-1 suppliers.
São Paulo stands as the undisputed economic engine of Brazil and Latin America, housing a massive concentration of automotive manufacturing (the historic ABC region), aerospace clusters, telecommunications networks, and heavy electrical engineering conglomerates. The transition towards green mobility and high-frequency power distribution systems has driven a substantial spike in demand for high-performance, high-conductivity metallurgical inputs.
For decades, local procurement teams have faced challenges regarding the raw purity and consistent mechanical yield of copper products. Sub-par oxygen content or trace impurities in standard copper rods can lead to devastating micro-cracking in high-speed CNC machining or premature electrical failure in electric vehicle (EV) charging busbars. As specialized manufacturers, we address this localized demand gap by supplying high-purity oxygen-free copper and high-conductivity tellurium/beryllium copper alloys engineered to international ASTM/EN specifications, delivered directly to São Paulo's leading industrial zones.
In the modern manufacturing environment, purchasing officers at multinational companies operating in Campinas, Guarulhos, and Bernardo do Campo require more than just competitive raw material pricing. Corporate governance demands complete compliance transparency: traceability from smelting to final delivery, environmental declarations, and strict compliance with global directives including RoHS, REACH, and ISO 9001:2015.
Sichuan Kepai New Material Co., Ltd. addresses these requirements by implementing complete chemical composition verification for every production run. Our localized supply chain protocols facilitate the seamless integration of raw material specifications into local manufacturing workflows, reducing quality assurance times and guaranteeing reliable performance inside high-pressure plasma cutters, automotive spot-welding rigs, and high-voltage grid connections.

Adapting raw material engineering to support next-generation industrial applications.
Electromobility platforms require high-current connections that can operate under high thermal stress. We are optimizing tellurium copper alloys (C14500) to support rapid charging systems, helping local assemblers improve conductivity and extend components' operational life.
To meet evolving environmental regulations, we are developing lead-free, high-machinability copper alloys. These products aim to match the cutting speeds of traditional leaded brasses while complying with RoHS restrictions for exports from São Paulo.
Modern wind and solar projects require copper with high resistance to environmental wear. We are refining our chromium-zirconium copper (C18150) formulas to help local utility component manufacturers improve structural performance in outdoor installations.
