COMPOSITE SECTION HAVING A SUPPORTING BASE OF LIGHT-WEIGHT METAL AND AT LEAST ONE METALLICALLY-JOINED, PROFILED STRIP AND PROCESS FOR MANUFACTURING A COMPOSITE SECTION

摘要

A composite section (10) features a base (12) of light-weight metallic material as section component and at least, one further profiled section component, in particular a profiled strip (18) of another metallic material which is joined metallically as a surface layer to the base section during an extrusion process. Projecting out of the inner-lying face (21) of the profiled strip (18) and directed at the base (12) is at least one projection and/or an additional element (23) which are/is embedded in the base (12). Each additional element (23) may delimit an undercut space which is filled in an interlocking manner by metallic material of the base (12).
