Bonded NdFeB magnets are manufactured with melt spinning of a thin ribbon of NdFeB alloy. This ribbon contains randomly oriented Nd2Fe14B nano-scale grains. Then, the ribbon is pulverized into particles and mixed with a polymer. At last, it is compressed into bonded neodymium magnets. Bonded NIB magnets are excellent choice over many other magnets which have limits on shapes. Bonded NdFeB magnets are widely used in micro motors, CD-ROM, DVD, personal stereos, phone vibrator motors, etc.
Features: hard and brittle; high demagnetization resistance; with coating or electroplating layer on the surface, bonded NdFeB magnets can have high erosion-resistance.
