Imanes de neodimio sinterizados son los imanes más potentes disponibles comercialmente en el mundo, con productos energéticos que oscilan entre 33 y 52 MGOe. Ofrecen una solución ideal para aplicaciones que requieren imanes fuertes y altamente coercitivos disponibles en grandes cantidades a un costo relativamente bajo. Los imanes de neodimio sinterizado se utilizan ampliamente en productos de consumo como teléfonos móviles, parlantes, sujetadores y juguetes, así como en aplicaciones industriales como detectores de metales, filtros de aceite, alternadores, medidores de flujo, y abrazaderas de soldadura. También son esenciales en máquinas de resonancia magnética, vehículos híbridos y eléctricos y turbinas eólicas debido a su alta potencia y tamaño compacto. Los imanes de neodimio sinterizado vienen en varias formas (bloques, anillos, arcos, discos, esferas y más), siendo el revestimiento de Ni-Cu-Ni el recubrimiento más común, aunque también hay otros acabados disponibles.
