Known as the Third Generation of Rare Earth magnets, Neodymium-Iron-Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnets today.
Sintered NdFeB offers the highest magnetic properties (33 MGOe to 51 MGOe).
Neodymium magnets offer the best value when comparing performance, size and cost. They are moderate in price, very strong magnetically, and typically allow for dimensional reductions.
