Sintered Neodymium Iron Boron (NdFeB), or “neo” magnets, is the third generation of permanent magnet developed in the 1980s. It offers the strongest magnetic power today. With its excellent magnetic characteristics Neodymium Magnet offers flexibility for new designs or is replacing older materials like Alnico and Ceramic in many applications, including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loud speakers. ndfeb neo ring

Why Choose Neodymium Magnet
A powder metallurgy process is used in producing sintered Neodymium magnets. Although sintered Neodymium magnet is mechanically stronger than Samarium Cobalt magnets and less brittle than other magnets, it should not be used as a structural component. Selection of Neodymium magnet is limited by temperature due to its irreversible loss and moderately high reversible temperature coefficient of Br and Hcj. The maximum application temperature is 200 °C for high coercivity grades. Neodymium magnet is more prone to oxidation than any other magnet alloys. If Neodymium magnet is to be exposed to humidity, chemically aggressive media such as acids, alkaline solutions salts and harmful gases, coating is recommended. It is not recommended in a hydrogen atmosphere.

Neodymium magnet has poor resistance to corrosion and they can also corrode from the inside-out if proper pre-treatment processes are not followed. Oftentimes, multi-layer Nickel-Copper-Nickel plating is applied to prevent failure from corrosion, but this preventative technique may not be sufficient for all applications.
