Machined metal component production comprises: fabrication of a metal sheet by casting, rolling and finishing operations; pre-machining the sheet on both faces; solution treatment of the pre-machined blank; tempering; and optional controlled traction, coating and/or cutting. Fabrication of a machined metal component comprises: (a) fabrication of a metal sheet by casting a rolling plate, optionally followed by homogenizing, one or more hot or cold rolling operations, optionally separated by one or more reheating operations, to obtain a sheet, and optionally one or more sheet cutting or finishing operations; (b) pre-machining of the sheet on one or both faces to obtain a pre-machined blank; (c) solution treatment of the pre-machined blank; (d) tempering treatment; (e) optionally, one or more stages of controlled traction, coating and cutting. Independent claims are included for: (a) use of the machined metal component as a structural element in aeronautical construction; and (b) an aluminum alloy structural element for aeronautical construction.
