Neodymium( NdFeB )magnets are the strongest type of rare earth magnet commercially available and are manufactured in wide range of shapes, sizes and grades. Zhaobao is bigger professional magnets manufacturer & exporter from China; We own one-step complete industrial chain from raw material blank, cutting, electroplating and standard packing.
Neodymium magnets are all graded by the material they are made of. As a very general rule, 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.
