Abstract

A method for preparation of an aluminum based alloy composition comprising forming by spray deposition, a solid body having a composition comprising, by weight, 5.5 to 8.45% Zn, 2 to 3.5% Mg, 0.5 to 2.5% Cu, 0.1 to 0.5% Zr, 0.3 to 0.6% Cr, 0.3 to 1.1% Mn, up to 0.5% Fe, up to 0.5% Si, other elements <0.05% each, up to 0.15% total, and balance Al. The body is converted to a worked product at 300.degree. to 450.degree. C., optionally converted cold, and heat treated in a series of steps comprising dissolution, quenching and annealing in a T6 or T7 state.
