摘要：
A magnetic core material for high frequency made of Fe-Co base alloy having excellent high frequency alternating current magnetic properties is disclosed, which contains 45 to 53 wt % of Co, 0.3 to 3 wt % of C, and 0.1 to 2 wt % of one or two of Mn and Si and, if necessary, 0.01 to 0.2 wt % of one, two or more of Mg, Ca and Ce, and balance of Fe and unavoidable impurities and in which the alloy has such structure that 1 to 20 % by volume of graphite is dispersed in a ferrite matrix. This material is used for dot printers and stepping motors.
