NdFeB Permanent Magnets N35-N52 Grade NdFeB Super Strong Powerful Magnets
Sintered Neodymium Iron Boron Magnets or "NdFeB" magnets offer the highest energy product of any material today and are available in a wide range of shapes, sizes and grades. NdFeB magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
Neodymium magnets are all graded by the material they are made of. The higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH.
