Product Description
NdFeB Magnet
Sintered NdFeB magnets have been commercially available since November 1984.
They offer the highest energy product of any material today and are available in a wide range of shapes, size and grades.
Earliest use of NdFeB magnets was primariy for voice coil motors(VCM's) in hard disk drives and this market still accounts for about 55% of the sales dollars.
Other applications include high performance motors, brushless DC motors, magnetic separator, magnetic resonance imaging, sensors and loudspeakers.
