Zusammenfassung:A stiff, lightweight metal laminate includes a first continuous metal layer, a second continuous metal layer, and a reduced density metal core layer disposed between the first and second continuous metal layers. The reduced density metal core layer comprises a core metal and has an average density that is less than the density of the core metal. Planar metallurgical bonds secure the first and second continuous metal layers to the reduced density metal core layer. The metal laminate may be manufactured by press rolling the reduced density metal core layer sandwiched between the two continuous metal layers, after removing or overcoating the native oxide layer on each layer surface that contacts another layer in the metal laminate.
