Title:
Ｆｅ基アモルファス合金薄帯、鉄心、及び変圧器
Document Type and Number:
Japanese Patent JP7192884
Kind Code:
B2
Abstract:
The invention relates to an Fe-based amorphous alloy ribbon having a first surface and a second surface, wherein Fe-based amorphous alloy ribbon has continuous linear laser irradiation marks on at least the first surface. The linear laser irradiation marks are formed in a continuous line by a continuous wave, CW oscillation method along a direction orthogonal to a casting direction of the Fe-based amorphous alloy ribbon, wherein a width WA along the casting direction of the linear laser irradiation marks on the first surface is 28.5 µm or more and 90 µm or less.
