Abstract
An AA7000-series alloy including 3 to 10% Zn, 1 to 3% Mg, at most 2.5% Cu, Fe <0.25%, and Si >0.12 to 0.35%, and a method of manufacturing these aluminum alloy products. More particularly, disclosed are aluminum wrought products in relatively thick gauges, in particular i.e. about 30 to 300 mm thick. While typically practiced on rolled plate product forms, this method may also find use with manufacturing extrusions or forged product shapes. Representative structural component parts made from the alloy product include integral spar members, and the like, which are machined from thick wrought sections, including rolled plate.
