The traits and applications of Bonded NdFeB

1.Traits: Br, Hcb and (BH)max are high, the cost performance is good. Easy processing various complex shape, various sizes and small specifications of products; Coating or the plating corrosion resistance is low.

2.Applications: Mainly used for office automation equipment, electrical machinery, audio-visual equipment, instrumentation, small motor and measuring machines, mobile phones, CD-ROM、DVD-ROM drive motor, hard disk spindle motor HDD, other micro & special dc motor and automated instrumentation, etc.
