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,boron
and 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
theorientation direction. Bonded magnet is isotropic and can be magnetized in
any direction magnetizing range is from 1koe-100koe which depend on
magnet 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.
