Abstract
A method for the manufacturing of an object. The method includes receiving a desired alloy composition for the object, depositing a plurality of foils in a stack to form the object, applying heat to the stack at a first temperature to bond the plurality of foils to each other, and applying heat to the stack at a second temperature to homogenize the composition of the stack. The homogenized stack has the desired alloy composition.

A cladded foil comprising:
- a core comprising a balance of Al and between 0-0.25 wt. % Si, between 3.5-3.8 wt. % Cu, between 0.3-0.9 wt. % Mn, and at least 1.2 and less than 1.45 wt. % Mg;
- and
- a cladding comprising a balance of Al and between 0.4-0.7 wt. % Si, between 4.8-5.2 wt. % Cu, between 0.3-0.9 wt. % Mn, and at least 1.2 and less than 1.45 wt. % Mg.
A cladded foil comprising:
- a core comprising a balance of Al and between 0-0.25 wt. % Si, between 3.5-3.8 wt. % Cu, between 0.3-0.9 wt. % Mn, and at least 1.2 and less than 1.8 wt. % Mg;
- and
- a cladding comprising a balance of Al and between 0.4-0.7 wt. % Si, between 4.8-5.2 wt. % Cu, between 0.3-0.9 wt. % Mn, and at least 1.2 and less than 1.8 wt. % Mg, and wherein the total thickness of the core and the cladding is less than 450 microns and the maximum thickness of the core is half of the total thickness of the core and the cladding.
