Soft Magnetic Materials Fe-based Nanocrystalline Ribbons

NANOCRYSTALLINE RIBBONS

Nanocrystalline Ribbon is a new type of Fe-based soft magnetic materials. Traditionally, metal crystalline materials with larger crystal grains were considered to have better magnetic characteristics. However, Nanocrystalline is invented with extremely small crystal grains ( at around 10nm, that’s why it is called Nano materials), considerably improve the magnetic characteristics.
