比黄金还贵的铁！中国超纯铁横空出世，美日的垄断暴利梦碎了！

Core Insights - A Chinese research team has successfully developed a high-purity iron known as "5N high-purity iron" with a purity level exceeding 99.999%, breaking the long-standing monopoly held by American and Japanese companies [1][3][10] - The production cost of this new material is only one-fifth of the import price, significantly impacting the international market and forcing foreign suppliers to lower their prices [1][8][9] Industry Impact - The semiconductor industry benefits from the use of domestic 5N2 high-purity iron, leading to a significant reduction in chip defect density and accelerating the advancement of 7nm technology, with Japanese suppliers forced to reduce prices by 37% [8][10] - The lifespan of aerospace engine blades has improved by 20% when using the new high-purity iron, enhancing performance under extreme conditions [8] - International suppliers, previously indifferent to Chinese demands, are now actively seeking long-term agreements, with Japanese suppliers reducing their prices from 200,000 yuan/ton to 120,000 yuan/ton, and major German and Korean companies placing large orders [8][10] Technological Breakthrough - The breakthrough in producing 5N high-purity iron was achieved through advanced vacuum zone melting technology, which required extreme precision and self-reliance in equipment development due to long-standing export restrictions from foreign countries [7][8] - The successful production of 5N2 high-purity iron marks a significant leap from the previous 4N8 level, demonstrating China's capability in high-end material manufacturing [5][7]
