Abstract
Manufacture of a light metal shock absorber by impact extrusion of the light metal of a steel-light metal composite blank, wherein the metallic bonding of the composite blank is achieved by coextrusion. The steel component on the bottom face of the light metal shock absorber is provided with a steel ring which is welded or otherwise appropriately joined during or after impact extrusion. Also the light metal sleeve of the shock absorber can, after impact extrusion, be welded or otherwise appropriately joined to light metal.
Claims8
