    Patent number: 4356618
    Abstract: A composite metal sheet or plate is manufactured by completely immersing an assembly of parallel or substantially parallel metal core sheets in molten metal at a lower melting point than the metal of the core sheets, and after the molten metal has solidified reducing the thickness of the ingot by hot rolling in a direction generally normal to the planes of the core sheets. The method has a particularly useful but by no means exclusive application in the production of reinforced aluminium alloy sheets and plates.
