An investigative study was carried out to understand the effect of homogenization, hot and cold rolling and annealing cycle on improvement of deep drawing and anodizing quality of thin AA3003-O sheets. Poor drawability of the sheets was attributed to coarse grain, high cube texture intensity and low average normal anisotropy (R ̅). The 2-stage homogenization cycle was optimized to maximize the conversion of β-phase (Al6(Mn,Fe)) to α-phase (Al(Mn,Fe)Si). The degree of hot rolling was increased to reduce the cube texture intensity in annealed circles. The annealing cycle was optimized to obtain the best combination of grain size, mechanical properties (UTS and total elongation), R ̅ and average planar anisotropy, ΔR. AA3003-O circles successfully passed the deep drawing test without any tearing or deformation, up to a draw ratio of 2. Also the presence of the α-phase led to an improvement in the anodizing quality of the final product.
