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 7.0-7.5 wt. % Si, between 2.6-3.0 wt. % Cu, and between 1.0-1.5 wt. % Zn;
- and
- a cladding comprising a balance of Al and between 10.0-11.0 wt. % Si, between 4.25-4.75 wt. % Cu, and between 2.0-2.5 wt. % Zn.
A cladded foil comprising:
- a core comprising a balance of Al and between 7.0-7.5 wt. % Si, between 2.6-3.0 wt. % Cu, and between 1.0-1.5 wt. % Zn;
- and
- a cladding comprising a balance of Al and between 10.0-11.0 wt. % Si, between 4.25-4.75 wt. % Cu, and between 2.0-2.5 wt. % Zn,
- wherein the proportions of the core and cladding are selected so that the homogenization of the core and cladding yields a 300-series aluminum alloy.
