ABSTRACT:
A component, particularly for land vehicles, preferably a car body component for motor vehicles, consists of a metallic foam material with a foamed porous layer comprising a metal powder and a blowing agent and possibly at least one solid metal sheet, there being metallic bonds between the solid metal sheet and the foamed porous layer. The component has at least one stamped contour which is raised from its surface, the angles, occurring in the region of the transitions between the three-dimensionally molded contour and the surface region being of the order of 100.degree. to 180.degree.. To produce the component, an essentially flat, metallic foam material, which is provided with solid metal sheets as covering layers, is initially shaped into a semi-finished molded product, which is end-contoured on one side, and the semi-finished molded product, so formed, is placed into a foaming mold, one wall of which is adapted to the end-contoured side of the semi-finished molded product, and foamed therein.
