The method according to the invention for producing a metal composite component is distinguished by the fact that the composite component (60) is provided with at least two portions (61, 62, 63) of different magnetization, wherein at least two portions (61, 62, 63) lie in direct succession on the one-piece component (60). The starting material for producing the composite component (60) is a semi-austenitic steel, which is provided as a cylindrical blank. The blank is subsequently formed into a desired shape of the composite component (60) and rendered magnetizable in a multistage forming and/or heat treating process, wherein the heat treatment is performed in such a way that the component has a saturation polarization Js = 0.9....1.5 T. This is followed by local heat treatment in one partial region while simultaneously cooling the regions of the composite component (60) that are not to be changed in their magnetic properties, in order to define strictly delimited transitional regions between the different regions of magnetization (61, 62, 63). The composite component (60) is suitable in particular for use in electromagnetic valves, for example including in the fuel injection valves of internal combustion engines. |
