Abstract
The invention relates to a magnetic screening for frequency fields between 50 Hz and 3000 Hz, made from a soft magnetic alloy of the following composition in wt. %: 30%.ltoreq.Ni.ltoreq.40%, 0%.ltoreq.Cu+Co.ltoreq.4%, 5%.ltoreq.Cr+Mo.ltoreq.17%, 5%.ltoreq.Cr 0%.ltoreq.Nb.ltoreq.2%, Mn.ltoreq.0.35%, Si.ltoreq.0.2%, C.ltoreq.0.050%, O.ltoreq.0.0160%, S.ltoreq.0.0020%, B.ltoreq.0.0010%, optionally at least one element selected from magnesium and calcium in amounts such that the sum thereof remains below 0.1 %, the rest being iron and production impurities. The chemical composition furthermore satisfies the following relationships: Cr+Mo.ltoreq.0.8.times.Ni+0.9.times.(Co+Cu) 18.4; Cr+Mo.ltoreq.4.times.Ni+3.times.(Co+Cu)-124; 4.times.(Cr+Mo).gtoreq.125-3.times.Ni. The invention further relates to use of said alloy for the production of low-frequency magnetic screening.
