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 1.0-1.6 wt. % Cu, between 0.9-1.3 wt. % Mg, and between 6.6-7.0 wt. % Zn;
- and
- a cladding comprising a balance of Al between 1.8-2.2 wt. % Cu, between 1.4-2.0 wt. % Mg, and between 8.0-8.6 wt. % Zn.
A cladded foil comprising:
- a core comprising a balance of Al and between 1.0-1.6 wt. % Cu, between 0.9-1.3 wt. % Mg, and between 6.6-7.0 wt. % Zn;
- and
- a cladding comprising a balance of Al between 1.8-2.2 wt. % Cu, between 1.4-2.0 wt. % Mg, and between 8.0-8.6 wt. % Zn,
- wherein the proportions of the core and cladding and selected so that the homogenization of the core and cladding yields an aluminum alloy having between 1.3-2.0 wt % Cu, 1.2-1.8 wt % Mg, and 7.0-8.0 wt % Zn.
