Abstract

A new family of medium and high strength, thermally stable aluminum based alloys are described having the following composition: 0.4 to 1.2% by weight chromium, 0.3 to 0.8% by weight zirconium, 1.5 to 2.5% by weight manganese, 0 to 2.0% by weight magnesium and the balance essentially aluminum. These alloys can be produced on a twin-roll caster preferably at a thickness of no more than 4 mm and a casting temperature of at least 820.degree. C.
