Work is reported on small-scale laboratory techniques described for development of high strength wrought aluminum alloys and on structure and properties of alloys produced. Alloy screening tests were on splat cooled samples and mechanical property measurements were from cast and rolled thin section cast plates. The highest tensile strengths obtained were in excess of 115,000 psi; highest yield strenghts were in excess of 110,000 psi. Four different alloys tested showed yield strengths in excess of 90,000 psi with elongations in excess of 5 pct.
