A list of Soft Magnetic Materials and Components
Electromagnetic Compatibility and Noise Reduction
Noise-reduction parts using materials―such as soft ferrite with excellent magnetic characteristics and FINEMET® nanocrystalline magnetic materials―are increasingly being utilized in automobiles, electronic products, and numerous other core fields.
Amorphous Coils and Core for Transformers (Metglas®)
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. Proterial provides amorphous metal ribbon.
Nanocrystalline Soft Magnetic Material FINEMET®
Proterial developed the first nanocrystalline soft magnetic material in the world, named “FINEMET®”. FINEMET® has high saturation flux density and high permeability. It also has stable temperature characteristics. FINEMET® provides excellent performance in electromagnetic noise suppression and contributes to energy saving. It will allow reduction in size and weight of electric and electronics devices as well. It is our hope, “FINEMET®” will be the best solution for your application due to its unique soft magnetic properties.
