摘要

Lightweight component consists of partially closed metallic outer wall body (12) and an inner region (13) made from a metallic foam. The inner region is formed as a core part (10) in the bearing region on the outer wall body with a core surface layer (14) and a core inner part (15). A cast metal layer having an interlocking and/or metallic connection surrounds the core part as an outer wall body. An Independent claim is also included for a process for the production of a lightweight component.
