Our factory is the top three of this size magnets producing, it's used for electroacoustics. Sintered neodymium iron-boron (NdFeB) magnets are the most powerful commercially available magnets in the world. With energy products between 28 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, and the abundance of raw materials available, 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.

NdFeB magnets contain iron and are very susceptible to corrosion. If they are to be exposed to moisture or corrosive elements of any kind, coating or plating is highly recommended. NdFeB magnets exhibit moderate mechanical properties, and are not excessively brittle, however they will crack or chip if dropped or allowed to snap together carelessly.

Sintered NdFeB magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe. ND-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes.
