Ímã Sintered
 
Ímã Sintered: é um dos ímãs permanentes da terra rara de desempenho elevado, que usam o neodymium (Nd), o ferro (Fe), e o boro (B) como seus ingredientes principais e são suscetíveis ao demagnetization quando expostos às temperaturas elevated. Há muitas classes que podem suportar altas temperaturas, mas diversos fatores ditarão o desempenho do ímã do neodymium. Há NdFeB sintered, alNiCo sintered, SmCo sintered e ferrite sintered.
