Abstract
This invention provides a metal laminate that maintains functionality such as radiation performance and is excellent in dimensional accuracy after press work. Such metal laminate is a roll-bonded laminate composed of 2 or more metal layers, which exhibits a ratio σ/T of the standard deviation σ of thickness T1 of the outermost layer to thickness T of the roll-bonded laminate of 0% of 4.0%, the thickness T of 2 mm or less, and the deviation of the thickness T of 4.0% or less.
Claims11
A roll-bonded laminate, comprising:
- two or more metal layers roll-bonded to each other, wherein an outermost layer of the two or more metal layers is selected from a group consisting of Al, an Al alloy, Cu, a Cu alloy, Mg, an Mg alloy, Ti, a Ti alloy, or SUS,
- wherein a ratio σ/T of a standard deviation σ of an outermost layer thicknesses to a thickness T of the roll-bonded laminate is 0% to 1.2%, and
- wherein the thickness T is 2 mm or less, and a deviation of the thickness T is 4.0% or less.
