A method is described for manufacturing a solenoid valve, in particular a fuel injector, the solenoid valve having a valve needle which is movably guided in the axial direction, a magnet core and an armature which is situated axially diametrically opposed to the magnet core, the armature being situated on the valve needle, the armature having a first base material and a first reinforcing element and the magnet core having a second base material and a second reinforcing element. The method has one method step. The first reinforcing element is applied to the first base material and/or the second reinforcing element is applied to the second base material during the method step with the aid of molten bath spraying or with the aid of cold gas spraying.
