Aimants en (di ferrite) yo devlope nan lane 1960 bonè la kòm yon altènativ a pri ki ba a aimants métalliques (aciers ak alnico), aimants en anpil tèt di, fasil pou kase. Estanda tolérances pou en Eman dimansyon se +/-. 005" pou tè dimansyon ak +/-2% mezi pou tankou: dimansyon. Paske rajilite yo aimants sa a pa reziste enpak oubyen flexing. Aimants en se chimique inèt ki pa-D', ki se yon benefis nan aplikasyon pou anpil.

Ceramic(Hard ferrite) magnets were developed in the early 1960 as a low-cost alternative to metallic magnets (steels and alnico), Ceramic magnets are very hard and brittle. Standard tolerances for ceramic magnet dimensions are +/-.005" for ground dimensions and +/- 2% of the size for as sintered dimensions. Because of their brittleness these magnets will not withstand impact or flexing. Ceramic magnets are chemically inert non-conductors, which is a benefit in many applications.
