Abstract
An aluminum alloy containing about 0.5 to 1.3% magnesium, about 0.4 to 1.2% silicon, about 0.6 to 1.2% copper, about 0.1 to 1% manganese, the balance substantially being aluminum along with impurities and incidental elements, is made into wrought wire, rod, bar or tube products by extrusion and cold working, preferably drawing, operations. The method includes extrusion within about 300.degree. or 400.degree. up to about 650.degree. or 700.degree. F. and even possibly up to 750.degree. or 800.degree. F. on a less preferred basis. Following extrusion, the product may be cold drawn either before or after, or both before and after, solution heat treatment and quenching. Rapid quenching is preferred. The product can then be artificially aged, for instance by heating to 375.degree. F. The resulting product has a fine grain size and consistent and good properties so as to be useful in a number of applications.
