AMORPHOUS ALLOY THIN STRIP

摘要

The present invention provides an amorphous alloy thin strip which is composed of Fe, Si, B, C and unavoidable impurities, and wherein: the amount of Si is from 8.5 atom% to 9.5 atom% and the amount of B is 10.0 atom% or more but less than 12.0 atom% when the total of Fe, Si and B is taken as 100.0 atom%; and the amount of C relative to the above-mentioned total of 100.0 atom% is from 0.2 atom% to 0.6 atom%. This amorphous alloy thin strip has a thickness of 10-40 mum and a width of 100-300 mm.
