自2007年6月起，本规范已被SAE航空航天材料部宣布为“取消”，并已被ASTM B 209、7075铝合金和7011取代。只要参考取消的AMS-QQ-A-250/26，应满足最新版ASTM B 209对7075铝合金和7011铝合金的要求。通过这一行动，本文件仍将列在航空航天材料规范索引的数字部分，并指出其已被ASTM B 209、7075铝合金和7011取代。本规范涵盖了铝合金、7011包铝、7075板材和薄板的具体要求；通用要求见AMS-QQ-A-250。本规范涵盖的板材和薄板应为整体复合产品，由可热处理的7075铝合金芯和7011铝合金阳极薄层组成，该铝合金阳极层与芯之间的厚度大致相等，并粘合到两个表面。

This specification has been declared "CANCELLED" by the Aerospace Materials Divison, SAE, as of June 2007 and has been superseded by ASTM B 209, alloy 7075 alclad with 7011. The requirements of the latest issue of ASTM B 209 for alloy 7075 alclad with 7011 shall be fulfilled whenever reference is made to the cancelled AMS-QQ-A-250/26. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications, noting that it has been superseded by ASTM B 209, alloy 7075 alclad with 7011.This specification covers the specific requirements for aluminum alloy, 7011 alclad, 7075 plate and sheet; the general requirements are covered in AMS-QQ-A-250. The plate and sheet covered by this specification shall be an integral composite product consisting of a heat-treatable aluminum alloy 7075 core with thin layers of a 7011 aluminum alloy anodic to the core and of approximately equal thickness, bonded to both surfaces.
