5、2006-01 Reaffirmed 2011-11 Superseding AMS 4123G Aluminum Alloy, Rolled or Cold Finished Bars and Rods (7075-T651) Solution and Precipitation Heat Treated (Composition similar to UNS A97075) RATIONALE This document has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE: 1.1 For
6、m: This specification covers an aluminum alloy in the form of bars and rods. 1.2 Application: These products have been used typically for machined parts subject to excessive warpage during machining due to residual stresses and for parts requiring high strength and whose fabrication does not involve
7、 welding or forming, but usage is not limited to such applications. 1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions. 2. APPLICABLE DOCUMENTS: The issue of the following
8、 documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding doc
9、ument has been specified, the last published issue of that document shall apply.
