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.
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.
