Abstract (en)

A method for producing a high strength aluminum alloy brackets, cases, tubes, ducts, beams, spars and other parts containing L1 2 dispersoids from an aluminum alloy powder containing the L1 2 dispersoids. The powder is consolidated into a billet having a density of about 100 percent. The billet is extruded using an extrusion die shaped to produce the component.
