ABSTRACT:
The invention concerns an alloy based on Al and essentially containing Li, Cu, Mg and Zr as its chief elements. It has good cold deformation capability, particularly when sheets or strips are being cold rolled, and good damage resistance, that is to say essentially good resistance to fatigue and corrosion under tension, and good fracture toughness. The alloy is of the following composition, by weight: from 1.7 to 2.25% Li; from 1.0 to 1.5% Cu; from 1.0 to 1.8% Mg; from 0.04 to 0.15% Zr; up to 2% Zn; up to 0.15% Fe; up to 0.15% Si; up to 0.5% Mn; up to 0.25% Cr; others: each .ltoreq.0.05%, total .ltoreq.0.15%; remainder Al. The alloy can be used as a structural element, particularly in the aircraft and space industries.
