NdFeB magnets, sintered NdFeb magnets, sintered ndfeb, anisotropy sintered ndfeb are available in both sintered and bonded forms. Sintered NdFeB offers the highest magnetic properties (33 MGOe to 51 MGOe) while Bonded NdFeB offers lower energy properties. Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets, they can be made in shapes and sizes that are difficult to achieve with sintering. High Power Permanent Magnet NdFeB Discs N45 D30x4.0mm, Gold Coated Magnetic Therapy Neo Circular Disc Magnets
Neodymium Disc Magnets, also called rare earth disc magnets, are the perfect combination of small size and maximum strength. With a diameter greater than the thickness, magnetic discs have a very strong magnetic field and high coercivity. This type of permanent magnet is used for different applications, such as metal separation, magnetic therapy, brochure closures, school science experiments, jewelry-making, packaging, book-binding, point of sale displays, and electrical appliances, just to name a few.
