Fe-based Amorphous Alloys Ribbons
Amorphous alloy is a new soft magnetic material. It is produced through an advanced technology of rapid solidification of molten metal at a cooling rate of about a million 'C/sec. During this process the metal is rapidly quenched as a form of ribbon with 25-35 µm in thickness, and the alloys show amorphous structure due to the high quenching rate.
Iron-based amorphous ribbon has many advantages, such as high permeability, high saturation induction, high electrical resistivity, high density, low core loss and good stability. It can replace the materials of silicon steel, permalloy and ferrites for soft magnetic applications. It is widely used in electronic products that high accuracy and good stability are the most required.
Applications
Inverter reactor, transformer core.
Wide constant permeable inductor core, PFC inductor core.
Mid-frequency transformer core, distribution transformer core.
Amorphous electromagnetic shielding materials for digital devices.
