我国突破超纯铁技术！十万吨仅含8公斤杂质，打破美日垄断

Core Insights - The breakthrough in producing 5N2 grade ultra-pure iron (99.9992% purity) by Shanghai University and Hebei Longfengshan marks a significant shift in the supply chain of ultra-pure materials, traditionally dominated by Japanese and American companies [1][3] - The new production method combines wet electrolysis, vacuum melting, and vertical zone melting, transforming previously sporadic successes into a repeatable manufacturing process [1][3] Group 1: Importance of Ultra-Pure Iron - Ultra-pure iron serves as a "stability amplifier" for high-end equipment, minimizing hidden risks associated with impurities like oxygen and nitrogen, which can affect performance in high-temperature environments [2][3] - Applications include soft magnetic components for electric motors, special alloy substrates for bearings and nickel-based alloys, and components for vacuum and semiconductor equipment, enhancing efficiency and longevity [2][3] Group 2: Cost Structure and Production Scale - The cost of ultra-pure iron has historically been extremely high, but the new production strategy aims to produce 800,000 tons annually, covering purity levels from 4N to 6N, thereby reducing costs through economies of scale [5][14] - A standard system for 38 application scenarios is being developed to translate purity levels into practical technical specifications for businesses [5][14] Group 3: Immediate Market Impact - Short-term benefits will primarily flow to three areas: large-scale rough purification, wet refining to raise purity levels, and vacuum zone melting for quality enhancement [7][8] - Key sectors poised to benefit include high-frequency electromagnetic devices, core components for vacuum equipment, and consistent alloys for aerospace and nuclear power applications [8] Group 4: Future Outlook - The essence of breaking the monopoly lies in transforming "bottleneck challenges" into calculable engineering problems, making ultra-pure iron as accessible and stable as essential utilities in manufacturing [11][13] - The competition in materials science is not just about achieving high purity in laboratories but about embedding technology into production lines, ensuring that ultra-pure iron becomes a common standard in Chinese manufacturing [13][14]
