This article is the first part of the series on pure iron materials, focusing on the basic concepts, historical background, and physical and chemical properties of pure iron. Pure iron is a high-purity iron material with excellent magnetic properties, soft magnetic characteristics, and corrosion resistance, widely used in electronics, medical, and industrial fields. Through this article, readers will gain an understanding of the core knowledge of pure iron, laying the foundation for subsequent a...

The pure iron market is increasingly dominated by a cost-driven race to the bottom, compelling major producers to scale back or discontinue high-grade lines. This shift towards non-standard materials, whose market share now exceeds 30%, has precipitated severe consequences: manufacturing failures, safety hazards, and significant reputational damage to "Made in China," as evidenced by multiple documented international incidents. This call to action outlines a firm commitment to reverse this trend...
