又是中国！20万一吨的“黄金”干成白菜价，美日垄断巨头彻夜难眠

Core Viewpoint - The global special materials market is experiencing a significant downturn, primarily driven by a drastic drop in orders from Japanese companies and a price war initiated to regain market share, leading to prices being slashed to one-third of their original levels [1][31]. Group 1: Market Dynamics - Japanese companies are facing a sharp decline in orders, with long-term contracts becoming burdensome [1]. - The U.S. is actively seeking collaboration with China after being pressured in its previously monopolized sectors [1]. - The catalyst for this global supply chain disruption is not rare earths but rather high-purity iron, which is essential for advanced manufacturing [1]. Group 2: High-Purity Iron Significance - High-purity iron, specifically at the "5N" level, is crucial for high-end manufacturing, with impurities needing to be limited to 4.5 parts per million [3][9]. - The presence of even minor impurities in high-purity iron can lead to catastrophic failures in semiconductor manufacturing and aerospace applications [11][13]. Group 3: Historical Context and Challenges - Historically, only the U.S. and Japan possessed the technology for extreme purification of iron, leading to high prices and strict contractual limitations [5][7]. - These limitations included prohibitions on the use of high-purity iron for critical applications, effectively stifling China's manufacturing capabilities [7][14]. Group 4: Technological Breakthroughs - A Chinese research team developed a novel approach to produce high-purity iron by sourcing higher purity raw materials instead of relying solely on complex purification processes [16][18]. - The team achieved a significant breakthrough by creating a production line capable of generating 4N purity iron, with plans to reach 5N purity [21][29]. Group 5: Competitive Landscape - By 2025, the Chinese team successfully produced 200 tons of 5N high-purity iron, significantly undercutting Japanese prices, which were previously set at 200,000 RMB per ton [31]. - This shift in production capabilities has forced Japanese companies to lower their prices and prompted U.S. firms to seek partnerships with China [31][32]. Group 6: Broader Implications - The advancements in high-purity iron production are expected to have a ripple effect across the entire high-end manufacturing supply chain, establishing a comprehensive patent protection system that could hinder U.S. and Japanese attempts to replicate the technology [34].
