Fe-based amorphous/nanocrystalline soft magnetic materials are prepared using advanced ultra-rapid solidification technology. Thanks to their excellent comprehensive magnetic properties—such as high permeability, high saturation magnetization, low coercivity, and low loss—they are widely used in various fields including power electronics, smart grids, smart homes, and new energy systems.

The Fe-based amorphous/nanocrystalline material has a thickness of 14–22 μm. The material preparation technology has further enhanced the performance advantages of amorphous/nanocrystalline materials, broadening their application prospects in emerging fields such as high-frequency transformers, common-mode inductors, and new-energy vehicles.
