SCOPE 1.1 Form This specific

6、ation covers an aluminum alloy in the form of sheet, clad on both sides with a different alloy. 1.2 Application This sheet has been used typically for formed structural parts of good strength, but usage is not limited to such applications. 1.2.1 Certain design and processing procedures may cause thi

7、s sheet to become susceptible to stress-corrosion cracking; ARP823 recommends practices 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 supplie

8、r 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 document has been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE Internationa
