Claim Text:
1. A method of making a metal laminate, the method comprising the steps of sequentially: a) 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 and a predetermined starting surface area; b) bonding together the first and second strips of the multilayer stack by rolling; and c) forming a finished laminate by reducing a thickness of the bonded-together first and second strips by rolling in at least one pass such that the starting surface area of the bonded-together first and second strips is increased by a factor of at least 25 and the one first metal strip has a thickness of 0.5 to 10 μm.
