Abstract
A connection arrangement between a casting made of light metal and a steel profile, wherein the steel profile is indirectly connected to the casting by way of a metallic coupling element having an open or a closed profile. One end of the coupling element is at least partially expanded and over-molded. Automotive components composed of one or more castings and steel profiles can be produced with this type of connection arrangement, which can have an arbitrarily complex structure. In a suitable manufacturing process, the coupling element can first be over-molded by a casting, which is constructed as a hollow component employing a casting core, and thereafter be materially connected to the steel profile, thus avoiding direct connection between the steel profile and the casting.
