Feature: Regarding the sintered NdFeB magnet:
the highest (BH)max reaches up to 51MGOe. The intrinsic coercive force is over 30,000 Oe. Surface treatments have been developed that allow them to be used in most applications. The treatments include gold, nickel, zinc, and tin plating and epoxy resin coating.
Common uses in different fields:
security systems, magnetic separators, magnetic resonance imaging, health bandages and plasters, specialty door catches, filters&strainers, sensors, speakers, microphone&earphone, motors, automobiles, magnetic coupling, chuck, magnetic toys, magnetic tools, other magnetic applications.
