摘要：
本发明公开了一种电池壳用铝合金板带及其制备方法，电池壳用铝合金板带含有的化学成分及各化学成分的质量百分比如下：Si：≤0.2％；Fe：0.5％～0.6％；Cu：0.05％～0.10％；Mn：0.06％～1.15％；Mg：≤0.03％；Zn：≤0.03％；Ti：0.02％～0.04％；不可避免的杂质元素：≤0.15％；余量为Al。它能够使其晶粒均匀一致，晶粒的直径可以小于50μm，保证其抗拉强度、屈服强度和延伸率等常温物理性能要求。
摘要（英）：

The invention discloses an aluminum alloy plate strip for a battery shell and a preparation method of the aluminum alloy plate strip. The aluminum alloy plate strip for the battery shell comprises chemical components including, by mass percent, 0.2% or less of Si, 0.5%-0.6% of Fe, 0.05%-0.10% of Cu, 0.06%-1.15% of Mn, 0.03% or less of Mg, 0.03% or less of Zn, 0.02%-0.04% of Ti, 0.15% or less of unavoidable impurity elements and the balance Al. Grains of the aluminum alloy plate strip can be uniform, the diameters of the grains can be smaller than 50 microns, and the extension strength, the yield strength, the ductility and other normal temperature physical performance of the aluminum alloy plate strip are guaranteed.
