Abstract

Aluminum alloys having compositions within the ranges (in Wt %) 0.2 to 3 lithium -0 to 4 magnesium -0.4 to 5 zinc -0 to 2 copper -0 to 0.2 zirconium -0 to 0.5 manganese -0 to 0.5 nickel -0 to 0.4 chromium-balance aluminum. The alloys are precipitation hardenable and exhibit a range of properties, according to heat treatment, which made them suitable for engineering applications where light weight and high strength are necessary.
