Future-oriented material compound systems are increasingly coming into play in lightweight construction. Conventional metals retain hereby a very high importance in large series lightweight construction, and the motivation to find stress-resistant materials remains unchanged. Thus, with their individual properties, various metals can make a significant contribution to both lightweight construction and function integration.

Components are usually fashioned from a single material due to the need for additional joining operations and to reduce the complexity. However, this means that the lightweight construction potential of the component often cannot be fully exploited. Conventional metal-to-metal joining concepts require a subsequent joining process through welding, gluing or mechanical joining. Due to such joints, the metal-to-metal compound casting concepts presented in the following are possible for various applications as they are directly integrated during the casting process of an aluminum component. This allows highly integrated and complex multi-material components to be realized with a reduction in the process steps.
