Sintered NdFeB magnets are produced by powder metallurgical process, which are the highest energy products at present.
They are widely used in the MRI, VCM, Motor, Separator, lifting, sensors and loudspeaker.
Feller can produce Sintered NdFeB magnets over 50 tons per month, many high capability magnets, such as
N48, N42M, N42H, N40SH, N30EH, are in mass production.
N30UHT is our new developed with low temperature-coefficient material, which can work well under high temperature at 180oC. It can replace SmCo magnets to reduce the cost in some fields, such as motors, generators and couplings.
The NdFeB magnets can be coated with Zn, CuNi, Epoxy and Phosphated. Phosphated treatment can work safely
under high temperature and make the magnets not come off the rotor shaft after gluing.
Bonded NdFeB is produced by a technique whereby a special form of NdFeB powder is blended with a plastic carrier material, die pressed and then heated. Parts made in this way can be of complex shapes and come off the tool with close tolerances, requiring no further finish machining. They have lower energy products than Sintered NdFeB - in the range of 10 MGOe. The Bonded NdFeB materials are isotropic - i. e. they can be magnetized in any direction.
The Bonded magnets are widely used in mobile, communication, computer, and micro-motor.
