Soft magnetic steel material having excellent DC magnetization

It is an object to provide a vibration-damping alloy which has a high power of damping vibration and can be used to make components of a structure, machine, etc. and reduce effectively any vibration thereof and the noise thereby produced. The vibration-damping alloy of this invention contains those proportions of Al and Si which fall within the range defined by a series of points in any of FIGS. 1 to 6, and less than 0.1 wt. % Mn, the balance of its composition being Fe and unavoidable impurities. It preferably contains more than 0.5 wt. % Si, while not containing more than 0.01 wt. % of any of C, N, O, P and S.
