The purpose of this SAE Aerospace Standard (AS) is to provide a description of the temper nomenclature system for aluminum alloys used in the aerospace industry by combining information from different sources for the benefit of the user.
Rationale
AS1990D stabilizes this document because equivalent technical requirements are contained in alternate documents.
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.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
