Explore our core selection of strategic materials engineering, including tellurium copper, lead bronze, and custom copper-nickel solutions designed for high conductivity and durability.
In modern precision engineering, the selection of raw materials dictates the operational boundary of structural systems. High-performance metals—specifically titanium alloys and high-conductivity copper alloys—have emerged as the two foundational pillars supporting aerospace innovation, new energy platforms, 5G signal networks, and laser-assisted micro-fabrication. While titanium alloys provide unmatched strength-to-weight ratios and high chemical stability at elevated temperatures, specialized copper formulations (such as Tellurium Copper and Beryllium Copper) serve the demands of dynamic electrical conduction, thermal dissipation, and complex machining.

We believe that only by continuously pursuing excellence and creating value can we win the trust of customers and the respect of society.
Operating in industries where component failure translates to critical system shutdown, we utilize strict statistical process control (SPC). Our quality assurance starts with direct raw material sourcing and proceeds through melting, extrusion, and cold drawing phases. Our physical and chemical testing rooms are stocked with state-of-the-art analytical instrumentation to evaluate microstructural integrity, alloy composition homogeneity, and precise tensile strength thresholds before shipment.
The company is located in the western area of the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108, boasting a superior geographical location and convenient transportation, which lays a solid foundation for the rapid development of the enterprise. Since its establishment, Kepai has adhered to the business philosophy of "innovation-driven development, quality wins the market," committed to providing customers with the highest quality high-end copper alloy materials, and promoting industrial upgrading and sustainable development.
As industrial platforms scale down in size while scaling up in performance, traditional metal alloys reach their mechanical limits. Our research division has mapped out a technical progression program targeting the development and processing of next-generation alloys. The focus centers on two critical metallurgical sectors: titanium alloy grain refinement and copper alloy electrical-mechanical property balancing.
Titanium alloys, particularly Ti-6Al-4V (Grade 5) and various beta-phase configurations, are highly sensitive to processing temperatures and deformation speeds. Our research centers on Vacuum Arc Remelting (VAR) and Electron Beam Cold Hearth Melting (EBCHM) to eliminate high-density inclusions and nitrogen-rich defects. By optimizing the thermomechanical processing parameters, we refine the grain structure down to the sub-micron scale, significantly enhancing the alloy's fatigue life and high-cycle stress limits. This is particularly vital for aerospace engine compressors, orthopaedic implants, and lightweight structural brackets.
Traditional copper alloys trade electrical conductivity for mechanical strength. Our patented aging and heat-treatment cycles bypass this limitation. By controlling the sub-microscopic precipitation of beryllium and nickel silicides in matrix alloys like C17200 and C17510, we achieve tensile strengths exceeding 1000 MPa while maintaining electrical conductivities above 45% IACS (International Annealed Copper Standard). This technological advance ensures that power connectors in 5G base stations and automotive relays operate with minimal heat generation, even under high electric currents.
Alloys engineered for extreme environments require integrated surface defense systems. Our development roadmap includes chemical passivation techniques and plasma-based vapor deposition methods that resist chloride-induced pitting in marine environments and prevent galvanic corrosion when titanium parts contact carbon-fiber composites. Our research group is focused on optimizing metal surface chemistry to eliminate heavy-metal runoffs, complying with the strictest environmental regulations in North America and Western Europe.
Providing specialized materials designed for critical operating environments across aerospace, heavy machinery, new energy vehicles, and telecommunications.
Weight reduction is directly tied to fuel efficiency and payload capacity. Our structural titanium alloys deliver high mechanical performance and corrosion resistance at a low density. Additionally, in satellite communications and rocket avionics, our custom high-strength copper alloys handle internal power distribution and signal routing. This ensures system stability under severe thermal cycles and high-vibration rocket launches.
High-voltage, fast-charging networks demand robust materials. Our high-conductivity C14500 Tellurium Copper alloys are the preferred material for EV charging gun contacts and high-current relays. The material's high machinability rating of 85% allows manufacturers to produce tight-tolerance components at scale, reducing tools wear and maintaining low resistance contact interfaces to prevent thermal runaway.
Signal integrity in microwave and high-frequency wave-guides requires extremely smooth interior surfaces and dimensional stability across temperatures. Our copper-nickel-beryllium alloys are widely used to manufacture coaxial connector pins, spring contacts, and electromagnetic shielding enclosures. These components maintain constant contact force over thousands of mating cycles without structural deformation.
Laser cutting nozzles and plasma torch electrodes demand maximum heat dissipation to prevent premature deformation. Utilizing Kepai's dispersion-strengthened copper and high-density oxygen-free copper ensures rapid thermal transfer away from the plasma arc. This prolongs tip lifetime, stabilizes cutting quality, and lowers operating costs for industrial manufacturing facilities.
Located in the industrial hub of Guanghan, Sichuan, near National Highway 108, Sichuan Kepai New Materials operates a lean, highly connected manufacturing framework. Our digital production process tracks materials from initial smelting to final packaging. By linking manufacturing execution systems (MES) with our physical testing laboratories, we maintain complete traceability for every batch of specialty alloys.
