Patent ID: 7819990

Claim:
An iron-cobalt alloy, characterized in that it comprises, in percentages by weight: from 10 to 20% of Co; from traces to 1.4% of Si; from traces to 1.4% of Al; from 0.1 to 1% of Mn; from 2 to 3% of Cr; from traces to 0.0100% of C; from traces to 0.0070% of O; from traces to 0.0070% of N; from traces to 0.0070 of S; from traces to 1% of V; from traces to 1% of Mo; from traces to 1% of Ta; from traces to 1% of Nb; a sum of the O, N and S contents of between traces and 0.0070%; a sum of the Si, Al, Cr, V, Mo and Mn contents of between 2.1 and 3.5%; a sum of the Cr, Mo and V contents of between 2 and 3%; a sum of the Ta and Nb contents of between traces and 1%; the balance being iron and impurities resulting from the smelting, in that: 1.23(Al+Mo) %+0.84(Si+Cr+V) %—0.15(Co %−15)≦2.1 and in that: 14.5(Al+Cr) %+12(V +Mo) % +25Si % ≧21, said alloy having a preferential axis texture <100> component deviating by less than 20° with respect to a hot rolling direction of grains for at least 30% by volume of the material.
