Sintered NdFeB
|
Sintered NdFeB magnets produced by a powder metallurgical process have the highest energy product to date. They are widely used in MRI, VCM, Motor, Separator, lifting, sensors and loudspeakers.
International Magnetic Solutions can supply Sintered NdFeB magnets with a variety of characteristics including:
N48
N42M
N42H
N40SH
N30EH
and
N30UHT
the newly developed low temperature-coefficient material, which can work well in high temperature up to 180ºC. It can replace SmCo magnets to reduce the cost in applications such as motors, generators and couplings.
The NdFeB magnets can be coated with Zn, CuNi, gold, epoxy and phosphated.
