This specification covers an arc-cast molybdenum alloy in the form of round bars 0.125 to 4.5 inches (3.00 to 112.50 mm), inclusive.
Rationale
AMS7819E results from a Five-Year Review and update of this specification that corrects the title of Table 2, requires agreement on properties outrside size limits (3.4.1.1.1), adds upper limit on size (Table 5), prohibits unauthorized exceptions (3.7), and revises reporting and marking for technical exceptions (4.4.2 and 5.1.1).
The committee of Titanium, Beryllium, and Refractory Materials, AMS Committee G, is responsible for preparation, revision, review and approval of documents related to aerospace application of these materials. Included are titanium, beryllium, and refractory metallic such as molybdenum, tantalum, and columbium. The committee provides a forum for interchange of experience and ideas among industry representatives, both suppliers and users, along with interested government agencies, to ensure the utility, proper technical content, and industry acceptance of published documents.
* 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.
