ABSTRACT:
The present invention relates to a rapidly quenched metal strip used as a core material for transformers, magnetic shields, choke coils, etc., and to an Fe-based rapidly quenched metal strip having a strip thickness exceeding 20 .mu.m and up to 70 .mu.m, wherein nonmetallic inclusions contained in said metal strip have a maximum particle size up to 50% of the strip thickness, and densities of the nonmetallic inclusions are up to 10 nonmetallic inclusions/mm.sup.3 for nonmetallic inclusions having a particle size exceeding 10 .mu.m and up to 50% of the strip thickness, up to 3.times.10.sup.3 nonmetallic inclusions/mm.sup.3 for nonmetallic inclusions having a particle size of at least 3 .mu.m to up to 10 .mu.m, and up to 5.times.10.sup.5 nonmetallic inclusions/mm.sup.3 for nonmetallic inclusions having a particle size of at least 0.3 .mu.m to less than 3 .mu.m, and showing the following average value <.epsilon..sub.f > of a bending fracture strain .epsilon..sub.f, being bent with the free surface of the film strip placed outside:
