In recent years, due to the fierce competition, many suppliers use special magnet composition like cheaper Lanthanum (La) or Cerium (Ce) to replace Praseodymium(Pr) or Neodymium(Nd) so as to reach lower magnet price to win more orders. In short time, customers can not judge magnet quality. But La or Ce is very dangerous to magnet quality and then application, because it will cause magnet to oxidize or even become powder in long time. We NEVER produce Neodymium magnet with La or Ce composition.
