sintered neodymium magnet(rings)

Rings neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals in rings sharps.
These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. Their max energy product can be 35MGOe~50MGOe, Neodymium magnets are developed rapidly and applied widely due to their perfect characteristic, rich raw material resource and reasonable price.

Neodymium magnets have a somewhat lower maximum operating temperature than other types of magnetic materials, so this should be considered when choosing a grade. Neodymium magnets (sintered NdFeB) are more powerful than any other permanent magnet material on the market today. Various grades of neodymium magnets are available with varying temperature and MGO characteristics. All neodymium magnets oxidize fairly rapidly when exposed, so an anti-corrosive coating (usually electroplating) is used to extend their useful lifespan. Extreme care must be excercised when handling neodymium magnets as they can easily pinch fingers. NdFeB magnets are not suitable for children because of it's strong magnetic strength.

Applications of sintered neodymium magnet(rings)
·Magnetic separators
·Microphone assemblies
·Servo motors
·DC motors (automotive starters) and other motors
·Computer rigid disc drives
·magnetic resonance imaging
·Various holders
Attributes of Neodymium Magnet
·Very high resistance to demagnetization
·High energy for size
·Good in ambient temperature
·Moderately priced
·Material is corrosive and should be coated for long
term maximum energy output
·Low working temperature for heat applications,
but higher levels of heat resistance materials
are being introduced periodically
