In the rapidly evolving landscape of global manufacturing, the demand for high-performance materials has never been greater. Oxygen Free Copper (OFC) with 99.97% purity represents the pinnacle of electrical and thermal conductivity. Unlike standard electrolytic tough pitch (ETP) copper, OFC is produced through a specialized smelting process in a vacuum or under a reducing atmosphere to eliminate oxygen and impurities. This results in a material that is not only highly conductive but also exceptionally resistant to hydrogen embrittlement, making it the preferred choice for sophisticated industrial hardware.
In the era of 5G and IoT, industrial hardware must handle massive data loads with minimal signal loss. Oxygen-free copper's 99.97% purity ensures stable signal transmission and low resistance. Connectors made from this material are essential for telecommunications infrastructure and high-speed data centers where reliability is non-negotiable.
EV industrial hardware, including busbars and charging connectors, relies on OFC to handle high currents. The absence of oxides prevents internal heating and improves the efficiency of battery management systems, directly impacting the vehicle's range and safety.

For industrial hardware used in vacuum environments, such as magnetrons and semiconductor processing equipment, 99.97% purity copper is vital. Its low volatility and resistance to gas release under high temperatures ensure that the vacuum integrity is maintained, preventing contamination of sensitive electronic components.
Solar inverters and wind turbine generators require heavy-duty industrial hardware that can withstand environmental stress. OFC provides the necessary ductility and thermal management properties to ensure long-term durability in green energy applications.

Established in 2017, Sichuan Kepai New Materials Co., Ltd. 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. Our products are widely applied in high-tech fields such as new energy vehicles, 5G technology, laser cutting, and lithium battery relays.
The global market for high-purity oxygen-free copper is witnessing a significant CAGR growth, driven by the "Electrification of Everything." As industries pivot away from fossil fuels, the efficiency of electrical conduction becomes a primary engineering constraint. We are seeing a trend toward "Ultra-High Purity" (6N or 99.9999% copper) for specific quantum computing applications, but 99.97% purity remains the "Golden Standard" for the majority of high-end industrial hardware due to its optimal balance between cost-efficiency and superior physical properties.
Furthermore, sustainability is shaping the industry. Sichuan Kepai is at the forefront of this by optimizing smelting processes to reduce carbon footprints while maintaining the 99.97% purity threshold. The integration of AI-driven quality control in our production lines ensures that every batch of industrial hardware material meets the rigorous standards of international aerospace and medical sectors.
Technological innovation is our core competitiveness. Our R&D team is composed of senior industry experts who keep pace with international cutting-edge technology trends. Through independent R&D and industry-university-research collaboration, Kepai has made breakthrough progress in high-performance tellurium copper, lead copper, and sulfur copper, reaching international advanced levels.

We adhere to the strategy of "rooted in Sichuan, radiating nationwide, and moving towards the world." Our culture of "integrity, innovation, collaboration, and win-win" drives us to provide the highest quality high-end copper alloy materials, promoting industrial upgrading and sustainable development globally.
