Embodiment 1
[0011] The production method of cast-rolled 1100 alloy aluminum foil for mobile phone battery casings in this embodiment includes: batching→smelting→cast-rolling→cold rolling→recrystallization annealing→cold rolling→edge trimming→low temperature tempering→foil rolling, wherein, In the cold rolling process, the billet obtained by casting and rolling is firstly cold-rolled to 3.0mm and then recrystallized annealed. The temperature of recrystallized annealed is 450°C and the annealing time is 20h; Reduction cold rolling, the pass processing rate of this embodiment is 60%, and finally the billet after large reduction cold rolling is rolled to the designed thickness of aluminum foil.
[0012] In the production method of cast-rolled 1100 alloy aluminum foil for mobile phone battery casings in this embodiment, the billet is cold-rolled to 3.0mm and then recrystallized and annealed. In this embodiment, the internal structure of the billet can be better improved by increasing the anneal...
