Abstract
This invention provides a roll-bonded laminate that is excellent in press workability and/or a roll-bonded laminate with improved performance and ease of handling at the time of production. More specifically, this invention relates to a roll-bonded laminate composed of a stainless steel layer and an aluminum alloy layer with the peel strength of 60 N/20 mm or higher, a roll-bonded laminate composed of a stainless steel layer and a pure aluminum layer with the peel strength of 160 N/20 mm or higher, and a roll-bonded laminate composed of a pure titanium or titanium alloy layer and an aluminum alloy layer with the peel strength of 40 N/20 mm or higher.
Claims6
A roll-bonded laminate, comprising:
- a stainless steel layer and a pure aluminum layer,
- wherein a total content of additive metal elements in the pure aluminum layer is 1% by mass or less,
- wherein a peel strength of the roll-bonded laminate is 160 N/20 mm or higher;
- wherein elongation measured by a tensile test is 50% or higher;
- wherein the pure aluminum layer has a thickness of 0.01 mm to 3.0 mm;
- wherein a reduction ratio of the pure aluminum layer is 10% or higher, and a reduction ratio of the roll-bonded laminate is 20% or lower;
- and
- wherein the roll-bonded laminate is batch annealed at 200° C. to 500° C., or continuously annealed at 300° C. to 800° C.
