Abstract
Disclosed is a method of making lithium-containing aluminum base alloy extrusion having at least a section thereof having a low aspect ratio or which is generally axisymmetrical, the extrusions having improved properties in sections thereof having the low aspect ratio or which are axisymmetrical. The method comprises providing a body of a lithium-containing aluminum alloy, pressing a portion of the body which is to form the axisymmetrical or low aspect ratio section through a tortuous path and extruding an axisymmetrical or a low aspect ratio extrusion section. The axisymmetrical or low aspect ratio section of the extrusion has a tensile strength of at least 60 ksi and an ultimate yield strength at least 4.5 ksi greater than the tensile yield strength.
