Abstract

A method of making a soft magnetic alloy by solidifying a melt with a composition which comprises (by weight): 47-50 % Co, 1-3 % V, 0-0.25 % Ni, 0-0.007 % C, 0-0.1 % Mn, 0-0.1 % Si, 0-0.15 % Nb, 0-0.3 % tantalum, where 0.14 ¤ (Ta +2Nb) ¤ 0.3, with the balance being Fe to form a blank. Hot rolling the blank followed by quenching from a temperature above 730 0C, pickled, then cold rolling followed by annealing at a temperature in the range 730-880 0C for 1-6 hours to give a yield strength in the range 200-450 MPa and a coercive field strength in the range 0.3-1.5 A/cm. The blank is hot rolled at a temperature in the range 1100-1300 0C while its thickness is reduced by 90 %. Cold rolling also reduces the bank thickness by 90 %. The alloy is used to make laminated electric motor rotors and stators.
