NdFeB Magnets is developed new type permanent megnetic material., which is the highest
magnetic properties.  NdFeB magnets allow small shapes and sizes. But NdFeB is senstive to
heat and should not be used in the environment that exceed 200 °C. And NdFeB magnets are more prone to oxidation than any other mangent alloy, so coating or plating is recommended for most application fields.
NdFeB are available in sintered as well as bonded forms.
However Sintered NdFeB has higher magnetic properties than bonded NdFeB. It is widely used in perament motors, engineering machines, audio equiments, electirc and medical devices and so on.
