Sintered neodymium iron-boron (NdFeB) magnets are the most powerful commercially available magnets in the world. With energy products typically between 33 and 52 MGOe, they are the perfect solution to a host of magnetic applications demanding very strong, highly coercive magnets that are available in large quantities at a relatively low cost.
Due to their impressive properties, their small size relative to their strength, NdFeB magnets are increasingly replacing those made from older materials such as ceramic and alnico, as well as other rare-earth materials such as samarium cobalt.
