Sintered NdFeB Magnet
Sintered NdFeB MagnetNeodymium Iron Boron is the third generation of Rare Earth Magnet,Website:, it is the strongest magnets in the world at present, its maximum energy product is up to 48 MGOe. NdFeB magnet is hard and brittle. Because the surface of Neodymium magnets is very easy to be rusted and oxidated in the air, so the surface treatments is necessary in order to hold close mechanical tolerances, such as: Zine coating, Nickel coating, Gold coating, electrophoretic coating, epoxy resin coating, passivation (temporary surface) etc.Due to its very high energy product, coercive force and high energy density , sintered NdFeB magnet are widely used in the moderm industry and electronic technology as the following fields:Acoustic field: speaker, receiver, micro, alarm, stage audio, car audio.Electrical and electronic: permanent magnetic actuator of vacuum circuit breaker, magnetic keep relay, a watt hour meter, water meter, meter sound, dry reed pipe, sensor.Motor areas: VCM, generator, motor, servo motor, micro motor, motor, vibration motor, etc..Mechanical equipment: magnetic separation, magnetic separation machine, magnetic suspension, magnetic machinery, etc..Healthcare: nuclear magnetic resonance instrument, medical equipment, health care products, such as magnetic fuel economizer.Physical properties of Sintered NdFeBItemUnitValueTemperature Coefficient of Br%/ C-0.11DensityG/cm37.3-7.6Vickers HardnessHv600Tensile Strengthkg/mm28Specific HeatCak(kg C)0.12kYoung s ModulusN/m21.6x1011Poisson s Ratio 0.24Curie TemperatureC310-340Electrical Resistivity.cm144Typical Magnetic properties of sintered NdFeBGradeRemanenceCoercive forceIntrinsic coercive forceMaximum energy productTwBrHcBHcJ(BH)maxkGsTkOekA/mkOekA/mMGOekJ/m3℃Nom.Min.Nom.Min.Nom.Min.Nom.Min.
