The tensile properties of 1050-aluminium sheets cold-rolled to 20%, 50%, 80%, 90%, 95%, and 96.7%, annealed to full recrystallization, are examined. The 90% and 96.7% cold-rolled sheets are annealed at different annealing temperatures for one hour. Their tensile properties are also examined and compared with those of the sheet cold-rolled to 95% prior to annealing. The microscopic structure through thickness, and surface and mid-thickness textures are investigated for the 96.7% cold-reduced sheet annealed at different temperatures for one hour. r45- and r^- -values show characteristic variation with an increasing annealing temperature for the 90%, 95%, and 96.7% cold-rolled sheets; they show peak values for the partially recrystallized state. This variation is qualitatively explained in correlation with textures obtained by means of X-ray pole figures. Heavily cold-reduced sheets annealed to full recrystallization are recommended for the improvement of press-formability.
