Abstract
Magnetic alloys of a ternary composition as defined within the region A, B, C, D of the ternary diagram of FIG. 5, wherein X is one or more metals selected from the group which consists of iron, nickel, aluminum, copper, molybdenum and manganese, are cast and rendered ductile by the formation within the material during solidification of at least two phases. One of the phases is preferably ductile and formed essentially of fibers or dendrites of Co and the other phase or phases are from those normally found in rare-earth/cobalt magnets. The alloy is magnetically hardened by precipitation hardening.
