摘要

Production of metal/metal foam composite components comprises inserting a flat or molded metal part into the hollow chamber of a casting mold; inserting a mixture of molten metal and propellant which is solid at room temperature; and foaming. An Independent claim is also included for a metal body produced by the process. Preferred Features: The propellant is contacted with the molten metal in a filling or casting chamber and then introduced to the hollow chamber.. The molten metal is made from aluminum or aluminum alloy. A die casting machine is used.
