Abstract
A method of producing an aluminum base alloy extruded product. The method comprises (a) providing a body of an aluminum base alloy; (b) homogenizing the body at an elevated temperature not exceeding its eutectic temperature for a sufficient period of time to provide a homogeneous distribution of the readily soluble alloy elements, (c) rapidly cooling the body; (d) reheating the body to a reheat temperature of at least 700° F. for a period of at least 0.5 hours; (e) extruding the body from the reheat temperature; (f) solution heat treating the body; and (g) quenching and aging the body.
