Neodymium-iron-boron magnet (NdFeB) Arnold Magnetic Technologies

Sintered neodymium-iron-boron (NdFeB) magnets, also referred to as "neo" magnets, have been commercially available since November 1984. They offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades. Earliest use of neo magnets was primarily for voice coil motors (VCM's) in hard disk drives and this market still accounts for about 55% of total sales dollars. Other applications include high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
