ABSTRACT:
Manufacture of a light metal shock absorber by impact extrusion of a light metal blank whereby, during the impact extrusion process itself, a steel strip is brought into contact with the base of the part which becomes free of obstructive light metal oxide as a result of impact extrusion and is as a result metallically bonded to the said base. The steel component of the composite body is provided with a steel ring which is welded or otherwise appropriately joined during or after the extrusion step. The light metal sleeve can be welded or otherwise appropriately joined to light metal after impact extrusion. The production of a light metal shock absorber is a special case of plastic deformation of light metal and the principles which lead to metallic bonding between light metal and steel or another metal are also valid here.
