电池盖用铝合金板
摘要：
本发明提供了一种防爆部整体成形型的电池盖用铝合金板。该铝合金板在利用冲压加工电池盖的同时也使防爆部与其一体成形，不仅可以使电池盒内的内压上升至最小限值即发生破坏，同时也不需要对冲压成形后的该防爆部的厚度进行逐个检测，并且不需要以强度调整为目的的退火处理。本发明所涉及的电池盖用铝合金板，其质量百分比构成为Fe1.15～1.35%、Mn 0.40～0.60%、另外还含有Ti 0.005%～0.15%、或Ti0.005%～0.15%与B 0.0005%～0.05%，剩余部分由Al和杂质构成，杂质中Si为0.15%以下、Cu为0.05%以下、Mg为0.05%以下。
摘要（英）：

The invention provides an aluminum alloy plate on a cell cover of which an explosion-proof part is integrally formed. The aluminum alloy plate utilizes stamping to manufacture the cell cover while theexplosion-proof part is formed integrally, thus allowing pressure in a cell chamber to increase to a minimum threshold causing break, without the need for inspecting the thickness of the explosion-proof part formed after the stamping one by one nor carrying out annealing for the purpose of adjusting strength. The aluminum alloy plate used for the cell cover provided in the invention has a qualitypercentage of Fe 1.15-1.35%, Mn 0.40-0.60%, Ti 0.005%-0.15% or Ti 0.005%-0.15% and B 0.0005%-0.05%. The remainder composition is Al and impurities in which Si is less than 0. 15%, Cu is less than 0.05% and Mg is less than 0. 05 %.
