Ultra-Wide Copper Plates Break Barriers 3800mm Ultra-wide Copper Plate

Empowering High-End Manufacturing and Serving National Strategic Needs

Recently, Nanjing Baotai Special Materials Co., Ltd. made a significant advancement in high-end copper plate production by successfully developing ultra-wide, high-precision copper plates measuring 3800mm in width using innovative rolling technology. This breakthrough establishes our company as a leading domestic manufacturer in large-scale plate rolling.

Breaking Width Limits and Overcoming Technological Challenges

Ultra-wide copper plates are a key basic material with significant strategic importance for domestic production. Domestic manufacturers have long relied on imports for large conductive components for offshore wind power, battery current collectors for new energy vehicles, and integrated circuit target substrates. NBSM's breakthrough shortens delivery cycles, reduces costs, and ensures the security of industrial and supply chains. The 3800mm ultra-wide copper plate is another one of the company's technological achievements in the field of non-ferrous metal specialty materials. It is made from a high-quality copper alloy base material and is processed through multiple precise steps, including rolling on a 3800mm wide plate rolling mill and finishing with a seven-roll leveling machine. With a maximum rolling length of 15 meters and a thickness of up to 200 millimeters, it possesses excellent characteristics, including high strength, high toughness, and corrosion resistance. Both dimensional accuracy and mechanical properties have reached internationally advanced levels.

Continuous Innovation Drives Industry Upgrades

This time, the production of the 3800mm ultra-wide copper plate not only broke through a series of key technical bottlenecks in equipment design, the rolling process, heat treatment, and surface quality control, but also achieved a comprehensive upgrade in product performance. Wide-width processing is an important development trend in the plate processing industry. However, every increase in width poses a significant challenge to equipment capabilities, process control, and personnel operation.

Targeting the characteristics of domestic special metal plate rolling, Nanjing Baotai's technical team has upgraded more than 10 key technologies of the imported wide-plate rolling mill. This upgrade solves industry problems such as uneven stress and edge cracking during the rolling process of ultra-wide plates. Looking ahead, Nanjing Baotai will continue to focus on major national needs and directions of industrial upgrading, increase R&D investment, and deepen industry-university-research cooperation. The company strives to become a world-leading manufacturer of high-performance materials and provide a solid material foundation for the vigorous development of China's high-end manufacturing industry.
