Sintered neodymium-iron-boron (NdFeB) magnets have been commercially available since 1983. NdFeB magnets offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades.
¡ôApplication field
Earliest use of NdFeB magnets was primarily for high property motors .such as voice coil motors (VCM's) in hard disk drives and this market still accounts for about 50% of total sales dollars¡¢brushless DC motors, Other applications include magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
¡ôProperty
Their (BH) Max value is about 6 to 10 times higher than sintered ferrite magnets; Hcj value is 5 to 10 times higher than sintered ferrite and 5 to 15 times higher than Alnico magnets. The potential magnetic properties of NdFeB magnets are very high, theoretically, their (BH) Max value can be as high as 527 KJ/M3(66MGOe), they can even attract object which weight is 640 times higher than themselves.
¡ôothers
NdFeB magnets also have some limitations due to their corrosion behavior. In humid applications, a protective coating is highly recommended. Coatings which have been used successfully include E-coat (a liquid dip epoxy coating), dry electrostatic spray epoxy, nickel plating and combinations of these coatings. Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature property. So now temperature stability of NbFeB still is poor. It is easy for losing magnetic properties under high temperature.
