PURPOSE:To obtain a magnetic alloy having superior square loop hysteresis characteristics by adding a specified improving component of square ratio and an increasing component of coercive force or a reducing component of coercive force to silicon steel contg. 4-8% Si. CONSTITUTION:This Fe alloy contains 4-8% Si and at least one kind of improving component of square ratio selected among <=3% each of Mo, W, Y and Ni and <=1% each of La, Ce, B and P. To the alloy may be added at least one kind of increasing component of coercive force selected among <1.0% C and <3.0% Cu or at least one kind of reducing component of coercive force selected among <=3% each of Ti, V, Cr, Zr, Nb, Ta, Co and Al, or <1.0% Mn, <=0.5% Ca and <=0.5% Mg. This magnetic alloy has square loop hysteresis characteristics with >=90% square ratio Br/B10 and is suitable for use as a material for an overcurrent detector, a magnetic amplifier, etc. |
