NdFeB magnets -The Strongest Permanent Magnets Today
NdFeB(Neodymium-Iron-Boron) magnet is used most popular by people in industry and our daily life, because it has superior magnetic properties than other kind of magnets. The outstanding characteristics are as follows:
·Higher unit magnetic properties than other magnet and assure you of smaller size and lighter weight in designing devices.
·Being mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust. To eliminate such a problem, the user should consider magnet coating, plating, or suitable surface treatment.
·Being less prone to chipping during handing
·Lower temperature coefficient of magnetic properties than ceramic but higher than SmCo type rare earth magnet. Therefore, this NdFeB type rare earth magnet will suffer irreversible loss at high temperature.
