  • Shaped & Sintered product which consists of rare earth elements called Neodymium (Nd), oxidzed iron (Fe), and Boron (B). It is widely used in extremely small and light products due to its super strong magnetic energy. 
    Moreover, Nd-Fe-B is less expensive than SmCo magnet, and this accelerate its use in various fields of business. However, its working temperature is quite low and it is easily oxidized, so surface treatment is very critical in the process of producing.
  •
