Fe-Cr-Co alloys have found application in the manufacture of permanent magnets on account of magnetic properties such as, high coercive force, remanent magnetization, and energy product. A method is disclosed for producing magnetic articles comprising Fe, Cr, and Co from powders comprising elemental or pre-alloyed particles. A powder is mixed with an essentially noncarbonizing organic binder, compressed, heated to remove binder, sintered, and aged. Heating results in essentially complete removal of binder prior to sintering. Magnetic bodies produced according to the disclosed method typically comprise less than 1 weight percent of undesirable nonmagnetic phases and have a maximum energy product of at least 1 million gauss oersted.
