1. the manufacturing method of a kind of press formability and the excellent aluminium alloy plate of shape freezing, which is characterized in that use BopingThe molten aluminium alloy that following compositions form is continuously cast into the tablet of 2~15mm of thickness by plate continuous casting machine, to the tabletUnreal applying heat roll but directly on roller after implement cold rolling, implement final cold rolling rate 70~95% cold rolling itAfterwards, using continuous annealing furnace, implement that 400~500 DEG C of temperature is kept to carry out also serving as admittedly for rapid cooling after being kept for 10~60 secondsThe final annealing of molten processing;

  • It is described into being grouped into:

    Mg containing 4.0~5.0 mass %, the Fe of 0.05~0.25 mass %, 0.005~0.10 matterThe Ti of % is measured, is limited to as the Si of impurity less than 0.20 mass %, remainder is substantially by Al and inevitably miscellaneousMatter forms.
