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, 9%<Co<20%, 6%<Cr<15%, 0%≦S≦0.5%, 0%≦Mn≦4.5%, 0%≦Al≦2.5%, 0%≦V≦2.0%, 0%≦Ti≦2.0%, 0%≦Mo≦2.0%, 0%≦Si≦3.5%, 0%≦C<0.05%, 0%≦P<0.1%, 0%≦N<0.5%, 0%≦O<0.05%, 0%≦B<0.01%, and the balance being essentially iron and having at least one of Al, V, Ti and Mo.
