ALUMINIUM RHEINFELDEN Group: The history of aluminium in Germany started at Rheinfelden. In 1898 Europe’s first river power station brought about the establishment of the first aluminium smelter in Germany, at Rheinfelden, Baden. The company has always operated in three business segments and in October 2008 restructuring turned Aluminium Rheinfelden GmbH into a holding company and the former ALLOYS, SEMIS and CARBON divisions became independent GmbH & Co. KGs (the German equivalent to a limited partnership with a limited liability company as general partner).
