A method for manufacturing a metal composite component is characterized in that the composite component () is provided with at least two sections () of different magnetization, at least two sections () being situated on the one-piece component () in direct succession. The starting material for manufacturing the composite material () is a semi-austenitic steel, which is provided as a cylindrical blank. The blank is subsequently shaped into an intended shape of the composite component () and rendered magnetizable in a multistage forming and/or heat treatment process, the heat treatment being performed in such a way that the component has a saturation polarization J=0.9-1.5 T. This is followed by a local heat treatment in a partial area under simultaneous cooling of the areas of the composite component () where the magnetic properties are not to be changed, in order to define strictly delimited transitional areas between the different areas of magnetization (). The composite component () is suitable in particular for use in electromagnetic valves, for example, including in fuel injectors of internal combustion engines.

The method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, is characterized in that the following method steps are used: a) providing a sheet metal strip made of a magnetic or magnetizable material, b) introducing an additive into a middle area of the sheet metal strip and fusing there for forming a non-magnetizable structure, c) cutting the sheet metal strip into a sheet metal piece of desired width, d) deforming the sheet metal piece into a sleeve shape, e) mutual fastening of the cut edges now facing each other and running in the longitudinal direction of the sleeve for forming a sleeve blank, f) final machining of the sleeve blank until a desired geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines.

A fuel injector for internal combustion engines, with a nozzle body in which a valve needle with a sealing face is movably supported. The sealing face of the valve needle comes into contact with a valve seat face that is adapted to the sealing face and is formed on an inner wall region of an end cup of the nozzle body. At least one injection opening is provided in the valve seat face, wherein both the inner wall region with the valve seat face of the nozzle body disposed on it and an outer wall region are hardened. The nozzle body is comprised of a rustproof martensitic steel that is hardened by means of case hardening with nitrogen.
