Forms of Amorphous & Nanocrystalline Soft Magnetic Materials

This is the most mature industrialized form with the largest market share. Amorphous ribbons feature high saturation magnetic flux density and low no-load loss, while nanocrystalline ribbons excel at low loss under high frequency and ultra-thin design.

Ribbons are mainly used for iron cores of current transformers, transformers and conventional magnetic components, representing the mainstream product in the current market.

The industrialization of this form has accelerated in recent years. It boasts light weight, low loss and excellent formability, and is suitable for medium-to-high frequency scenarios and components with complex structures, for which magnetic powder is the preferred material.

Powders are widely applied in magnetic powder cores, integrated inductors, EMI filters and composite wave-absorbing materials, serving as a fast-growing application with great potential.

Bulk materials (thickness ≥ 1mm) are still in the cutting-edge R&D stage. Manufactured via vacuum injection molding, they are characterized by integral forming, high saturation magnetic flux density and superior mechanical strength, yet their current application scope remains limited.

They are primarily used for hinge components of foldable smartphones, precision parts inside watches, medical implants and core components of micro instruments, which belong to niche and concealed application fields.
