Abstract:
It is an objective of the present invention to provide a metal laminate material, which has sufficient strength as well as molding processability, lightweight properties, and radiation performance, which is a metal laminate material that has a two-layer structure of a stainless steel layer and an aluminum layer or a three-layer structure of a 1st stainless steel layer, an aluminum layer, and a 2nd stainless steel layer, wherein tensile strength TS is 200≤TS≤550 (MPa), elongation EL is not less than 15%, and a surface hardness Hv of the stainless steel layer is not more than 300 for the metal laminate material.

Claim (Index 4):
A method for producing the metal laminate material having the two-layer structure of the stainless steel layer and the aluminum layer according to  claim 1 , which comprises:\n a step of sputter-etching a stainless steel foil having a surface hardness Hv of not more than 300; a step of sputter-etching an aluminum foil having a surface hardness Hv of not less than 20; and a step of pressure-bonding a sputter-etched side of the stainless steel foil and a sputter-etched side of the aluminum foil at a reduction rate of not more than 10%, thereby obtaining the metal laminate material having the two-layer structure of the stainless steel layer and the aluminum layer.
