The invention concerns an iron-cobalt alloy, characterised in that it comprises in weight percentages: 10 to 22% of Co; traces to 2.5% of Si; traces to 2% of Al; 0.1 to 1% of Mn; traces to 0.0100% of C; a total of O, N and S content ranging between traces and 0.0070%; a total of Si, Al, Cr, Mo, V, Mn content ranging between 1.1 and 3.5%; a total of Cr, Mo and V content ranging between traces and 3%; a total of Ta and Nb content ranging between traces and 1%; the rest being iron and impurities resulting from production; and in that: 1.23x(Al+Mo)%+0.84 (Si+Cr+V)%-0.15x(Co%-15)<=2.1 and in that 14.5x. (Al+Cr)%+12x(V+Mo)%+25xSi%>=21. The inventive alloy is useful for making electromagnetic actuator mobile cores. |
