Amorphous Coils and Core for Transformers from freeamfva's blog

Amorphous metal is an alloy with a non crystalline structure produced by ultra-rapid quenching (about 1 million ℃ per second) of molten alloy. Because amorphous metal has no anisotropic properties, which originated from a crystalline structure, and there are no crystalline grain boundaries to prevent motion of magnetic domain walls, it shows excellent magnetic properties such as high permeability and low loss while having a high-saturation magnetic flux density. Amorphous metal materials for transformers, whose main ingredient is Fe (iron), are used in power line transformers and industrial transformers. Compared to conventional materials such as silicon steel, amorphous metal materials have a small no-load loss (iron loss), 1/5 that of silicon steel. Therefore, they make a major contribution to energy conservation. Hitachi Metals provides amorphous metal ribbon.Get more news about Amorphous core,you can vist our website!

Amorphous magnetic cores allow smaller, lighter and more energy efficient designs in many high frequency applications for Invertors, UPS, ASD(Adjustable speed drives), and Power supplies (SMPS). Amorphous metals are produced in using a rapid solidification technology where molten metal is cast into thin solid ribbons by cooling at a rate of one million�C/second. Amorphous magnetic metal has high permeability due to no crystalline magnetic anisotropy.

Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials. These cores can offer superior design alternative when uses as the core material in the following components:
Where typical ferrite cores can only operate up to a flux saturation level (Bsat) of 0.49 Tesla, amorphous metal cores can be operated at 1.56 Tesla. Combined with operating at permeability similar to high-end ferrites and the flexibility of manufacturing large cores sizes these cores can be an ideal solution for many of these components.
