本规范涵盖了标称厚度为0.250至3.000英寸（含0.250至3.000英寸）的焊接和非焊接应用的两种锻造铝合金装甲板（见6.2）。锻造铝合金AA6055装甲的可焊性仅适用于该厚度的II级装甲；1.500‰Û. AA6061变形铝合金装甲的可焊性尚未确定。因此，这种合金应该用作贴花盔甲。

This specification covers two wrought aluminum alloy armor plate for both welded and non-welded applications in nominal thicknesses from 0.250 to 3.000 inch, inclusive (see 6.2). The weldability of wrought aluminum alloy AA6055 armor has been determined for Class II armor for this thicknesses, only; 1.500‰Û. The weldability of AA6061 wrought aluminum alloy armor has not been determined. Therefore, this alloy should be used as appliquÌ© armor.
