A soft magnetic alloy comprises (by weight): 47-50 % Co, 1-3 % V, 0-0.2 % Ni, 0.08-0.12 % Nb, 0-0.007 % C, 0-0.1 % Mn, 0-0.1 % Si, with the balance being Fe and impurities. A soft magnetic alloy comprising (by weight): 47-50 % Co, 1-3 % V, 0-0.2 % Ni, 0.08-0.12 % Nb, 0-0.005 % C, 0-0.1 % Mn, 0-0.1 % Si, with the balance being Fe is processed by hot rolling followed by cold rolling and then annealing at a temperature in the range 730-880 0C. The alloy can be hot rolled at a temperature in the range 1100-1300 0C, with a thickness reduction of 90 %. After hot rolling the alloy is preferably quenched to room temperature from 730 0C or more, pickled and then cold rolled with 90 % reduction in thickness. Used for making laminated electric motor stators and rotors. |
