Abstract: Alloys having the nominal composition in weight percent 30 percent cobalt, 15 percent chromium, 5 percent manganese, 0.05 percent carbon, remainder iron, when cold worked to an area reduction of at least 50 percent and annealed at a temperature of 500 degrees to 650 degrees C. for a time of from one minute to 10 hours, exhibit a square hysteresis loop, medium coercive force, and high residual induction, enabling their use in a variety of magnetic devices such as bistable switches and memories.
