    Properties, Grades, Surface Treatments, and Applications of Neodymium Magnets

    Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal system formed by neodymium, iron and boron (Nd2Fe14B). In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet is greater than the samarium cobalt magnet, which is the largest magnetic energy product in the world […]

    The 9 Differences between Neodymium Magnets and Ferrite Magnets

    1. Chemical Composition: Neodymium Magnets: Primarily composed of neodymium (Nd), iron (Fe), and boron (B), neodymium magnets are a type of rare earth permanent magnetic material. Ferrite Magnets: Mainly composed of iron oxides, typically a composite of magnetite (Fe3O4) and other metal oxides. 2. Appearance Differences: Neodymium Magnets often require electroplating to prevent rust and […]
