Abstract
An iron-based amorphous alloy thin strip for wound transformers has a composition expressed by a chemical formula: EQU Fe.sub.a B.sub.b Si.sub.c Mn.sub.d where about 78.ltoreq.a.ltoreq. about 82 at %, about 8.ltoreq.b.ltoreq. about 15 at %, 4.ltoreq.c.ltoreq. about 14 at %, and about 0.2.ltoreq.d.ltoreq. about 1.0 at %. The ratio (building factor) of the iron loss of a wound core obtained from the above-described alloy thin strip to the iron loss of a single strip is about 1.5 or below.
