Fe-based amorphous ribbons are advanced soft magnetic materials composed primarily of iron, designed for high-efficiency magnetic applications. Produced through rapid solidification processes, these ribbons feature a non-crystalline atomic structure that delivers superior magnetic properties compared to conventional crystalline alloys.

Known for their high saturation magnetic flux density and low core loss, Fe-based amorphous ribbons are widely used in transformer cores, power inductors, electric vehicle components, solar inverters, and high-frequency magnetic circuits. Their excellent thermal stability, high electrical resistivity, and efficient energy conversion characteristics make them ideal for both low- and medium-frequency applications.

These ribbons offer an optimal balance between performance and cost, providing compact and energy-efficient solutions for modern power electronics and smart grid systems. They are available in various thicknesses, widths, and edge treatments to suit different design requirements and fabrication processes.
