6、 and Identification (5.1.1), and is a Five-Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers an aluminum alloy in the form of sheet and plate up to 2.000 inch (54.80 mm) inclusive, in thickness (see 8.5). 1.2 Application This product has been used typically fo
7、r structural applications requiring material with high strength and resistance to exfoliation-corrosion, 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 practi
8、ces to minimize such conditions. 2. APPLICABLE DOCUMENTS The issue of the following 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 i
