A METHOD OF FORMING A FERROUS ALLOY WITH HIGH EMERGY MAGNETIC PROPERTIES WHICH COMPRISES MELTING TOGETHER 6 TO 9.6 WEIGHT ALUMINUM, 12 TO 16 WEIGHT PERCENT NICKLE, 22 TO 34.5 WEIGHT PERCENT COBALT, 0.70 TO 3.5 WEIGHT PERCENT COPPER, A METAL SELECTED FROM THE GROUP CONSISTING OF UP TP 0.41 WEIGHT PERCENT ZIRCONIUM AND UP TO 5.2 WEIGHT PERCENT TITANIUM, AND THE BALANCE BEING IRON; COOLING SAID ALLOY, HEATING SAID ALLOY TO A TEMPERATURE IN THE RANGE OF 1050* C. TO 1100* C., DEFORMING SAID ALLOY AT A TEMPERATURE IN A RANGE OF 1050* C. TO 1100* C. TO A PREDETERMINED SHAPE, AND SUBJECTING SAID ALLOY TO A HIGH ENERGY MAGGNETIC FIELD TO IMPART HIGH ENERGY MAGNETIC PROPERTIES THERETO.
