Fe-based Amorphous Ribbon

Description

Amorphous Ribbon is an new soft magnetic material. It is produced through the advanced technology of rapid solidification of molten metal at a cooling rate of about a million ℃/sec. During this process the metal is rapidly quenched as a form of ribbon with 25-35 μm thickness, and the micro-structure of the alloy is the amorphous due to the high quenching rate.

Fe-based Amorphous Ribbon has many advantages, such as high permeability,high saturate induction, high electrical resistivity, high density,low core loss and good stability. It can replace the materials of silicon steel, permalloy and ferrite. It is widely used in electronics products that high accuracy and good stability are the most required.

Application

Inverter reactor, transformer core.
Wide constant permeable inductor core, PFC inductor core.
Mid-frequency transformer core, distribution transformer core.
Amorphous electromagnetic shielding material for digital devices
