Abstract
At least about 0.1 percent by weight of indium is added as an essential component to an alloy which precipitates a T.sub.1 phase (Al.sub.2 CuLi). This addition enhances the nucleation of the precipitate T.sub.1 phase, producing a microstructure which provides excellent strength as indicated by Rockwell Hardness values and confirmed by standard tensile tests.
