Hybrid casings from the same material offer a high potential for lightweight construction and recycling. Hybrid aluminum-aluminium cast nodes were produced via low pressure die casting. To evaluate the transition area characteristics micro indentation tests, mechanical wedge test and a combined three-point bending peel test of hybrid test parts were used. To predict the melting of the extruded aluminum parts in the casting process a simulation of thermo couples in Magmasoft 5.4.1 was used. The results were used for the production of a demonstrator sub frame geometry with integrated aluminium profiles.
