About Neodymium Iron Boron Magnets
Collectively known as Neodymium Iron Boron magnets,it is alloy of the Lanthanide group of elements that Composed by neodymium, iron, boronand a few transition metals like Dysprosium, Gallium .etc, Through these melting ,pressing, sintering, machining, Coating, magnetizing processes, to form those what we called block, bar,Cubic, cylinder, ring,arc shapes.
NdFeB magnets are available in sintered as well as bonded forms. The bonded form need almost no machining yet tolerance is small, The flux of the bonded form is up to 10 MGOe while sintered form available to reach 52 MGOe. The sintered form usually requires some finishing operations in order to suit mechanical tolerances. ndfeb super magnets
Plating NdFeB is a difficult process, coating,acidification,passivation each process should be acidity soft and temperature friendly . Zinc, Nickel, NiCuNi and Epoxy plating providegood corrosion resistance and nice appearance for NdFeB magnets.
All Sintered NdFeB magnets are anisotropic that can only be magnetized in the orientation direction. Bonded magnet is isotropic and can be magnetized in any direction magnetizing range is from 1koe-100koe which depend on magnets’ size, grade and what the magnets for.
As the most advanced commercialized permanent magnet materials, NdFeB magnets are available in a number of different grades that span a wide range of properties and application requirements.
