Abstract

Fine grained Fe-Cr-Co magnetic alloys are disclosed which have desirable magnetic alloys in the range of 300-600 Oersted, 8000-13000 Gauss and a maximum energy product of 1-6 MGOc. Disclosed alloys comprise 25-29 weight per cent Cr, 7-12 weight per cent Co with the remainder Fe. Processing of disclosed alloys to produce a fine grain includes a low-temperature solution annealing between 650-1000 DEG C, depending on the composition, followed by rapid quenching, cold shaping and a step-ageing heat treatment at decreasing temperatures from 700 DEG C to 480 DEG C, optionally in a magnetic field. The alloys can be used as ringers, relays and electro-acoustic transducers.
