ABSTRACT:
Aluminium alloys having compositions within the ranges (in wt %) 2 to 2.8 lithium--0.4 to 1 magnesium--1 to 1.5 copper--0 to 0.2 zirconium--0 to 0.5 manganese--0 to 0.5 nickel--0 to 0.5 chromium--balance aluminium. The alloys are precipitation hardenable and exhibit a range of properties, according to heat treatment, which make them suitable for engineering applications where light weight and high strength are required.
