Abstract

A method for producing a high strength aluminum alloy tubing containing L12 dispersoids from an aluminum alloy powder containing the L12 dispersoids. The powder is consolidated into a billet having a density of about 100 percent. The tube is formed by at least one of direct extrusion, Mannesmann process, pilgering, and rolling.
