PCT No. PCT/GB83/00229 Sec. 371 Date Jun. 4, 1984 Sec. 102(e) Date Jun. 4, 1984 PCT Filed Sep. 19, 1983 PCT Pub. No. WO84/01391 PCT Pub. Date Apr. 12, 1984.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.
