ABSTRACT:
Aluminum based alloy primarily for use in aircraft and aerospace components consists essentially of the composition: 2.60 to 3.30 weight percent copper, 0.0 to 0.50 weight percent manganese, 1.30 to 1.65 weight percent lithium, 0.0 to 1.8 percent magnesium, and from 0.0 to 1.5 weight percent of grain refinement elements selected from the group consisting of zirconium, and chromium. Up to about 0.5 wt. % zinc and up to about 1.5 wt. % titanium may also be present. Minor impurities may also be present. These alloys exhibit an improved combination of characteristics including low density, high strength, high corrosion resistance and good fracture toughness.
