Abstract: The effects of homogenizing, middle and final annealing processes on strength and toughness of AA1100 foil were investigated by optical microscopy, transmission electron microscopy and mechanical property tester. The results show that the properties of alloy are: σ_b≥120MPa, δ ≥20% and the best strengthening and toughening effect of this foil is achieved by adopting 560 ℃, 16 h homogenizing and 230～260 ℃, 1 h final annealing. The strengthening and toughening mechanism of the material is also discussed.
