ABSTRACT:
Methods for making an aluminum drive shaft for automobiles or trucks or other drive shaft applications from aluminum alloy tube and methods for making said tube including using an aluminum alloy containing about 0.5 to 1.3% magnesium, about 0.4 to 1.2% silicon, and about 0.6 to 1.2% copper and preferred practices for making the tube. The preferred practices include extrusion temperature and other aspects of extrusion, along with cold drawing. One preferred practice includes reducing tube diameter and increasing wall thickness at one or both ends of the drive shaft tube shortly after solution heating and quenching and applies to various 6000 Series type aluminum alloys.
