摘要： A metal laminate is made by first laying at least one first metal strip of at least one first metal having a thickness of 40 μm to 750 μm on at least one second metal strip of a second metal different from the first metal to form a multilayer stack having a total thickness between 2 mm and 15 mm. Then the first and second strips of the multilayer stack are bonded together by rolling. Finally a finished laminate is formed by reducing a thickness of the bonded-together first and second strips by rolling in at least one pass such that the one first metal strip has a thickness of 0.5 to 10 μm.
