In the rapidly evolving landscape of global industrial manufacturing, the demand for materials that exhibit "Excellent cold processing performance" has shifted from a preference to a strategic necessity. As a leading OEM manufacturer and supplier, Sichuan Kepai New Materials Co., Ltd. recognizes that the ability to shape materials at ambient temperatures—without compromising structural integrity or conductivity—is the cornerstone of Industry 4.0 precision engineering.
Information Gain: Unlike traditional hot-working methods that can induce thermal stress and oxidation, cold processing (including cold heading, deep drawing, and precision stamping) enhances the material's yield strength through strain hardening. Our proprietary alloys, such as OFT Oxygen-Free Tellurium Copper, are engineered to maintain a delicate balance between high plasticity and ultimate tensile strength, allowing for complex geometries in EV connectors and aerospace micro-components.
The global copper alloy market is currently witnessing a paradigm shift driven by the electrification of everything. From the 5G infrastructure rollout to the exponential growth of the New Energy Vehicle (NEV) sector, the technical requirements for conductive materials have reached unprecedented levels. Cold-processed copper alloys are at the heart of this revolution.
The push for decarbonization is driving demand for high-purity, oxygen-free copper alloys. Manufacturers are now prioritizing materials with low electrical resistance and high thermal dissipation, especially for AI data centers and high-speed rail systems.
Kepai’s technical roadmap focuses on the refinement of grain structures. By optimizing the "Cold Forming Ratio," we achieve alloys that are harder yet more ductile, reducing tool wear in high-speed CNC environments.
Our production adheres to ISO 9001:2015, ISO 14001:2015, and IATF 16949 standards. We ensure full compliance with RoHS and REACH regulations, providing our global partners with a reliable, conflict-free supply chain.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength free cutting tellurium copper and other special copper alloys. Our focus on technical innovation has led to the development of Oxygen-free and highly conductive tellurium copper alloy with independent intellectual property rights.
With an investment in state-of-the-art manufacturing facilities spanning 29,000 square meters, we have positioned ourselves as a global leader in the copper alloy industry, serving over 1,000 customers worldwide with a reputation for precision and reliability.
Our "Excellent cold processing performance" materials are utilized in diverse, high-stakes environments:
High-conductivity copper for charging piles, battery connectors, and high-voltage distribution units. Cold processing ensures tight tolerances and vibration resistance.
Micro-miniature connectors and generators require C17200 Beryllium Copper with extreme elastic properties, achievable through cold drawing and precision aging.
Bactericidal copper alloys for surgical instruments and antimicrobial surfaces in healthcare facilities, leveraging copper's natural biological properties.
Heat-treatable Ni-Si precipitation copper with outstanding softening resistance.
The benchmark for deep drawing, stamping, and complex cold heading applications.
High-performance elastic alloy with superior wear and corrosion resistance.
Premium tin-phosphorus bronze optimized for high fatigue reliability.
Free-cutting Beryllium Copper with added lead for precision industrial fittings.
Extreme strength foil for high-end electronic connectors and spring clips.
The "King of Free-Cutting" brass, ideal for high-volume automated machining.
Highest strength available in copper alloys (up to 1380 MPa).
Our in-house metallurgists control every stage of production, from vacuum induction melting to final precision drawing.
Developed high-conductivity oxygen-free tellurium copper, reducing hydrogen embrittlement risks in brazing processes.
Focusing on environmentally friendly sulfur-copper alloys (C14700) to meet global green manufacturing mandates.
Our alloys undergo a proprietary homogenization process that ensures a uniform grain structure. This minimizes cracking during severe plastic deformation and allows for higher deformation ratios in cold heading and deep drawing applications.
Yes, C14500 is specifically designed for free-cutting performance. The addition of tellurium acts as a chip breaker, allowing for higher CNC spindle speeds and superior surface finishes compared to pure copper.
We use high-purity cathode copper and perform melting under controlled atmospheres to keep oxygen levels below 10ppm. This ensures conductivity levels reach 90-98% IACS, critical for high-power connectors.
Absolutely. We are IATF 16949 certified, which is the stringent quality management standard for the automotive supply chain. Our materials are used by major Tier 1 and Tier 2 automotive suppliers globally.
Yes, our R&D team can adjust the chemical composition (e.g., beryllium, cobalt, or nickel content) to meet specific mechanical or electrical requirements of your project.
As we look toward 2030, Sichuan Kepai New Materials Co., Ltd. is investing in "Computational Materials Engineering" to predict alloy performance at the atomic level. We are committed to developing the next generation of "Ultra-High Strength, Ultra-High Conductivity" alloys that will power the next era of fusion energy research, quantum computing interconnects, and deep-sea exploration vessels. By choosing Kepai, you are not just choosing a supplier; you are partnering with an innovator dedicated to pushing the boundaries of what is possible with copper.
