Abstract
It is an object of the present invention to provide a roll-bonded laminate controlled in warping and a method for producing the same. The method produces the roll-bonded laminate having a two-layer structure of a first metal layer and a second metal layer, by roll-bonding a first metal plate and a second metal plate, wherein the surface hardness Hv of the first metal plate is lower than the surface hardness Hv of the second metal plate; and the method comprises roll-bonding so as to satisfy the following expression (1):0<(Δ)/≤38 (1)wherein ΔL(mm) represents an elongation amount of the first metal layer with respect to the first metal plate; ΔL(mm) represents an elongation amount of the second metal layer with respect to the second metal plate; and T (mm) represents the total thickness of the roll-bonded laminate.
