Seventeen experimental heat-treatable Al-Zn-Mg-Cu alloys and four Al-Mg or Al-Mg-Zn strain-hardenable alloys were evaluated for suitability as cartridge case materials. Sixteen alloys were of low impurity level achieved by use of refined 99.99 Al ingot as base metal and were rolled to .015 inch and .063 inch sheet by practices developing high degrees of homogeneity. Five alloys were of moderate purity. Comparisons among alloys were made on basis of strength-toughness characteristics, corrosion resistance, temperature stability, quench sensitivity, annealing characteristics and grain size properties.
