Explore our leading selection of high-performance copper materials optimized for modern industrial hardware, custom electrical component manufacturing, and rugged engineering applications.
In the rapidly evolving landscape of global manufacturing, material integrity dictates the performance boundaries of industrial systems. The C11000 copper plate, chemically classified as Electrolytic Tough Pitch (ETP) copper, stands as the cornerstone of electrical power, automotive manufacturing, and heavy-duty machinery hardware. With a minimum copper purity of 99.90%, C11000 exhibits an extraordinary electrical conductivity rating of at least 101% IACS (International Annealed Copper Standard). This makes it the undisputed material of choice for engineering components that require minimal electrical resistance and maximum thermal dissipation.
Industrial hardware encompasses a massive array of components, including heavy-duty busbars, switchgear contacts, electrical enclosures, grounding terminals, precision washers, and heat exchanger assemblies. In these applications, copper plates are subjected to extreme environmental stresses, high mechanical loads, and continuous electrical currents. Choosing high-grade C11000 copper plates ensures that these critical hardware components maintain operational efficiency, minimize power losses, and resist localized thermal degradation under strenuous conditions.
What makes the C11000 copper plate uniquely suited for industrial hardware applications is its balanced metallurgical profile. The presence of controlled oxygen within the ETP copper matrix optimizes its conductivity while maintaining excellent cold and hot workability. Unlike lower-grade alloys, C11000 responds exceptionally well to shearing, punching, stamping, drawing, and forging operations, allowing hardware manufacturers to produce complex shapes with minimal tool wear.
Achieving 101% IACS electrical conductivity and 388 W/m·K thermal conductivity, ensuring minimal energy loss and efficient heat transfer in high-power systems.
Superb response to cold working, stamping, bending, and deep drawing. Ideal for intricate hardware configurations and automated mass production lines.
Forms a protective oxide layer that shields the material from atmospheric moisture, industrial chemicals, and saline environments, guaranteeing longevity.
C11000 copper plates are extensively deployed across multiple high-tech and traditional industrial sectors:
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 for the national 13th Five-Year Plan, 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. The products are mainly applied in high-tech fields such as new energy vehicles, 5G technology, laser cutting, and lithium battery relays.
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.

Technological innovation is the core competitiveness of Sichuan Kepai New Materials Co., Ltd. The company has a research and development and production team composed of senior industry experts who keep pace with international cutting-edge technology trends and continuously explore the unknown boundaries in the field of new copper alloy materials. Through a combination of independent research and development and industry-university-research collaboration, Kepai has made breakthrough progress in several areas, including high-performance tellurium copper, lead copper, and sulfur copper. Many of its technological achievements have reached international advanced levels and have been successfully applied in various industries such as new energy vehicles, precision machining parts, plasma cutting, relays, and energy storage, earning widespread recognition and praise in the market.
Kepai's product line is rich and diverse, covering a comprehensive range of solutions from basic materials to high-end customization. We focus on providing customers with high-performance, high-quality high-end copper alloy products, including but not limited to pure copper, oxygen-free copper, oxygen-free high-conductivity tellurium copper, nickel tellurium copper, tin bronze, beryllium copper, lead bronze, sulfur copper, and chromium zirconium copper. These products play an important role in reducing production costs and enhancing product performance due to their excellent physical and chemical properties and environmental friendliness, creating significant economic and social benefits for customers.
In the face of global market competition, Sichuan Kepai New Materials adheres to the development strategy of "rooted in Sichuan, radiating nationwide, and moving towards the world." By continuously optimizing market layout and improving the sales network, we have established a stable customer base in multiple provinces and cities across the country and have formed long-term cooperative relationships with several internationally renowned enterprises. At the same time, the company actively expands into overseas markets, participates in international competition and cooperation, and strives to promote Kepai's brand influence on the global stage.
We understand that the long-term development of an enterprise is inseparable from an excellent corporate culture. We advocate the corporate spirit of "integrity, innovation, collaboration, and win-win," encouraging employees to explore boldly and innovate courageously, while also emphasizing teamwork and talent cultivation, striving to create a harmonious, open, and inclusive work atmosphere. We believe that only by continuously pursuing excellence and creating value can we win the trust of customers and the respect of society.
As industrial automation, robotics, and smart grids expand, the demands placed on electrical hardware components are shifting. The integration of IoT sensors inside electrical switchgears and motor housings requires materials that can handle both heavy power loads and high-frequency signal transmissions. C11000 copper plates are increasingly being integrated with conductive surface platings (such as silver, tin, or nickel) to prevent surface oxidation while maintaining maximum contact conductivity in humid or corrosive industrial atmospheres.
Furthermore, the automotive transition to 800V architectures in electric vehicles demands busbars with tighter tolerances and higher thermal thresholds. Sichuan Kepai is at the forefront of this shift, refining our manufacturing processes to supply C11000 copper plates with superior flatness, optimized grain structures, and exceptional punch-and-bend characteristics. This reduces fracturing during high-speed stamping, allowing automotive suppliers to accelerate throughput and reduce material waste.
While C11000 offers unmatched physical properties, processing ETP copper requires specialized engineering knowledge. ETP copper can exhibit high ductility, which sometimes leads to "gummy" behavior during high-speed machining or drilling. To solve this, Kepai provides tailored annealing states (ranging from soft annealed to hard tempers) to match the customer's specific fabrication processes. Whether you are using laser cutting, CNC milling, or progressive die stamping, our technical team works directly with your engineers to deliver C11000 plates that maximize machining efficiency and minimize burr formation.
We leverage state-of-the-art production lines and precision testing instruments to guarantee the chemical composition and mechanical performance of every copper plate.
Our copper products are trusted in key markets worldwide, complying with rigorous international standards for purity, mechanical properties, and environmental safety.
