自2010年12月起，本文件已被SAE航空材料部宣布“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，表明其已被“取消”。本规范涵盖挤压棒材形式的铝合金。这些挤压件通常用于要求中等强度的零件，并且必须将加工过程中的变形降至最低，但使用不限于此类应用。这些挤压件用于不需要AMS 2772热处理技术要求和质量保证规定的应用。

This document has been declared "CANCELLED" by the Aerospace Materials Division, SAE as of December 2010. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications indicating that it has been "CANCELLED".This specification covers an aluminum alloy in the form of extruded bars and rods.These extrusions have been used typically for parts requiring moderate strength and where distortion during machining must be minimized, but usage is not limited to such applications.These extrusions have been used for applications which do not require the technical requirements and quality assurance provisions of AMS 2772 heat treatment.
