Abstract:
New alloys for potential use in applications such as in lower wing skins and fuselage skins are disclosed. Specifically, Mn-free 2×24 alloys potentially suitable for thick plate and thin plate and sheet applications are believed to be novel and to provide unexpectedly superior properties.

Abstract:
An improvement to a process for treating an aluminum alloy for the series AA 2000 or AA 6000 comprising solution heat treating, quenching and natural or artificial aging, in which conventional heat solution heat treating is defined as solution heat treating the alloy at a temperature which is 5.degree. to 10.degree. C. below a known eutectics melting temperature for the alloy. The improvement comprises solution heat treating at a temperature which is 10.degree. to 100.degree. C. below the conventional solution heat treating temperature in order to desensitize the alloy to intercrystalline corrosion.
