ABSTRACT:
A wide amorphous alloy thin strip having a width of 70 mm or above and useful as an iron core of electric power transformers, composed of Fe--Si--B--C amorphous alloy. Dispersion of an amorphous structure in the width direction is prevented and deterioration of the strip properties is suppressed by adding Mn or by casting in an atmosphere containing a carbonic acid gas in an amount of about 40 vol % or more to thereby control strip surface roughness to a center line average surface roughness of about 0.7 .mu.m or less.
