Abstract
A magnetic component for a magnetically actuated fuel injection device is formed of a corrosion resistant soft magnetic alloy consisting essentially of, in weight percent, 3%<Co<20%, 6%<Cr<15%, 0%≦S≦0.5%, 0%≦Mo≦3%, 0%≦Si≦3.5%, 0%≦Al≦4.5%, 0%≦Mn≦4.5%, 0%≦Me≦6%, where Me is one or more of the elements Sn, Zn, W, Ta, Nb, Zr and Ti, 0%≦V≦4.5%, 0%≦Ni≦5%, 0%≦C<0.05%, 0%≦Cu<1%, 0%≦P<0.1%, 0%≦N<0.5%, 0%≦0<0.05%, 0%≦B<0.01%, and the balance being essentially iron and the usual impurities.
