PROBLEM TO BE SOLVED: To obtain an Fe-Co based soft magnetic material in which the design of an alloying is applied so that desired electromagnetic properties and mechanical properties can be obtained. SOLUTION: The Fe-Co based soft magnetic material consists of an Fe based alloy having a composition containing, by mass, 30 to 37% Co, 1.5 to 2.7% V, 0.1 to l.5% Ti, 0.1 to 2.0% Si and 0.01 to 0.1% Al, and the balance Fe with inevitable impurities. Among the compositional ratios (expressed by %) of each element, the relation shown in the following inequalities of 1.185<=(2Co+4 V-53)/(9Si+8Ti+16Al), 0.880<=(Co+7Si+10Ti)/(83-14V-8Al), and 1.008<=(Si-0.4Ti+1.5)/(V+2Al) is valid. |
