Abstract: 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.

Abstract: A continuous hot bonding method for producing a bi-material strip with a strong bond therebetween is provided. The method comprises sanding a first strip formed of steel; and applying a layer of first particles, typically formed of copper, to the sanded first strip. The method next includes heating the first strip and the layer of the first particles, followed by pressing a second strip formed of an aluminum alloy onto the heated layer of the first particles. The aluminum alloy of the second strip includes tin particles, and the heat causes the second particles to liquefy and dissolve into the melted first particles. The first particles and the second particles bond together to form bond enhancing metal particles, which typically comprise bronze.
