This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing produced with cross sectional area of 32 in2 (206 cm2) maximum.
Rationale
AMS4491 is a new document for 2024-T81 extrusions to allow for the stabilization of AMS-QQ-A-200/3.
The committee of Nonferrous Alloys, AMS Committee D, shall prepare, coordinate, and revise documents related to nonferrous metals technology, such as aluminum, magnesium, and copper, through the participation of metals suppliers, users, and interested government agencies. Committee activities shall provide a forum for the cooperative interchange of ideas and experience of the participants, resulting in the publication of specifications that embody sound, established aerospace industry practices and requirements to serve the suppliers and customers of aerospace materials.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
