6、A-250/5. 1. SCOPE 1.1 Form This specification covers an aluminum alloy in the form of alclad sheet and plate supplied in the -T3/-T351 temper. 1.2 Application These products have been used typically for medium strength parts requiring formability and maximum corrosion resistance and whose fabricatio
7、n does not involve welding, but usage is not limited to such applications. 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 d
8、ocument 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 International, 400 Commonwealth Drive, Warrendale, PA
