Abstract

Aluminum-base alloys which are provided which possess highly desirable properties, such as relatively low density, high modulus, high strength/ductility combinations, strong natural aging response with and without prior cold work, higher artificially-aged strength than existing Al-Li alloys with and without prior cold work, weldability, good cryogenic properties, and good elevated temperature properties. In one embodiment, aluminum-base alloys are provided having Al-Cu-Li-Mg compositions in the following ranges: 5.0-7.0 Cu, 0.1-2.5 Li, 0.05-4 Mg, 0.01-1.5 grain refiner selected from Zr, Cr, Mn, Ti, Hf, V, Nb, B, TiB2, and mixtures thereof, and the balance essentially Al. In another embodiment, aluminum-base alloys are provided having Al-Cu-Li-Mg compositions in the following ranges: 3.5-5.0 Cu, 0.8-1.8 Li, 0.25-1.0 Mg, 0.01-1.5 grain refiner selected from Zr, Cr, Mn, Ti, Hf, V, Nb, B, TiB2, and mixtures thereof, and the balance essentially Al.
