Abstract: In a method for manufacturing structural components from an extruded section, especially consisting of Al, Mg or their alloys, which after its exit from the die of the extrusion press, is guided by one or a plurality of guide tools for the purpose of forming it as a straight or arc-shaped (rounded) section, an end section is separated by a separating tool and in the hot state, is fed by means of gripping tools to a hot-forming process and successively to one or a plurality of processing stations.

Abstract: The invention relates to a method for manufacturing thin-walled pipes, which are made of a heat-resistant and wear-resistant aluminum-based material. The method comprises the spray-compacting of a thick-walled pipe made of a hypereutectic aluminum-silicon AlSi material, possibly a subsequent overaging annealing, and the hot deformation to a thin-walled pipe. Such a method is in particular united for the production of cylinder liners of internal combustion engines, since the produced liners exhibit the required properties in regard to wear resistance, heat resistance and reduction of pollutant emission.

Abstract: A process is disclosed for manufacturing thin-walled pipes made of a heat- and wear-resistant aluminium-based material. A billet or tube blank made of a hypereutectic AlSi material is produced, optionally overaged by an annealing process, then extruded into a thick-walled pipe or round bar. The thus obtained preform is severed and extruded into a thin-walled pipe. This process is particularly suitable to manufacture light metal cylinder liners for internal combustion engines, since the thus manufactured cylinder liners have the required properties regarding wear-resistance, heat-resistance and lowered pollutant emissions.
