The description of magnets:
NdFeB (Neodymium-Iron-Boron) – is the most powerful rare-earth
permanent magnet, because of this, it called
super magnet or
strong magnet . NdFeB magnet was developed from the year of 1983 and became commercially available in 1984.
Neodymium magnet have the highest Br, and BHmax of any magnet formula, 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 magnet.
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
The Nd-Fe-B permanent magnets, which are called the next centurial magnets, are used in a wide range of industries including computer, automobile, electric machinary, electro-sound devices, automatic control, magnetic force mechanism, microwave commnication, petrochemical industry, medical apparatus and equipment. The magnets are the ideal materials for the subminiature magnetic devices with high function.
