自2012年1月起，SAE航空航天材料部已宣布本规范“取消”。通过这一行动，本文件将保留在《航空航天材料规范索引》的数字部分，并指出其已被“取消”。本规范涵盖片状铝合金。本产品用于成型的结构零件，这些零件随后将进行热处理，并要求具有高强度和良好的耐腐蚀性，但用途不限于此类应用。

This specification has been declared "CANCELLED" by the Aerospace Materials Division, SAE, as of January 2012. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Materials Specifications, noting that it has been "CANCELLED".This specification covers an aluminum alloy in the form of sheet.This product is used for formed structural parts, which will be subsequently heat treated and require high strength and good corrosion resistance, but usage is not limited to such applications.
