Product Description
China Manufacturer Supply Magnetic Material Custom Magnets Neodimio Imanes
In 1984, Sagawa, Hadjipanayis, and Croat independently discovered Neodymium magnet nearly at the same time. The main phase of Neoymium magnet is Nd2Fe14B and maximum energy products achieved 280kJ/m3 at that time. The successful development of Neodymium magnet announced the birth of the third-generation rare earth permanent magnet. Neodymium magnet also referred as NdFeB magnet because they are composed primaryly of Nedymium (Nd), Iron (Fe), and Boron (B). Neodymium magnet can be classified to sintered Neodymium magnet, Bonded Neodymium magnet, and hot-pressed Neodymium magnet according to the detailed manufacturing process. Sintered Neodymium magnet still offers the strongest magnetic power nowadays and has been widely served to vast kinds of application, include high-performance permanent motors, brushless DC motors, magnetic separators, magnetic resonance imaging (MRI), sensors, loudspeakers, consumer electronics, and green energy.
