Neodymium Iron boron magnets, a sort of Rare earth magnet metrial ,has the high remanence,high coercive force, high Maximum energy and easily formed into various sizes,shapes.So  they have widely used in commercially available fields since the mid-1980's
     It  can be manufactured by sintering,compression bounding,injection molding and extrusion ,The sintered from holds a lower energy product of up to 48MGOe,While  the bonded from hold a lower energy ,product of up to 10MGOe .Furthermore,the majority of Ndfeb magnets are anisotropic and can only be magnetized in the orientation direction.
      Ndfeb magnet are prone to corrosion in humid environment ,It usually need surface
treatment according to customer's requirements to protect magnet.
