Scope
This specification covers the engineering requirements for heat treatment of aluminum alloy castings and for parts machined from castings.
Rationale
AMS2771F results from limited scope ballots with changes to refrigeration equipment (3.1.5), solution treatment batch furnace interruption (3.2.6.1), quenchant temperature rise (3.2.9.4.1), refrigeration processing (3.2.10.2), solution treatment (Table 1) for A201 and A206, and adding A206-T71 precipitation treatment (Table 2).

Issuing Committee
AMS D Nonferrous Alloys Committee
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.
