Abstract

A method for manufacturing a part including steps of (1) casting an ingot, (2) scalping the ingot to yield a scalped ingot, (3) homogenizing the scalped ingot to yield a homogenized ingot, (4) breakdown of the homogenized ingot to yield a slab, (5) rolling the slab to yield a rolled aluminum material, (6) annealing the rolled aluminum material to yield an aluminum starting material, (7) cold working the aluminum starting material to obtain an aluminum cold worked material, and (8) forming the part from the aluminum cold worked material.
