6、ar Review policy. 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temper. 1.2 Supersession Notice Requirements for thin gage sheet (0.008 to 0.187 inch) in accordance with AMS4041 are superseded by AMS4462. AMS-QQ-A-250/5 a

7、nd AMS4462 have the same requirements for alclad thickness and tensile properties for material less than 0.187” in thickness. 1.2.1 AMS4041 covers alclad material for sheet greater than 0.187 inch, and plate. The cladding thickness is minimized to provide a commensurate increase in tensile propertie

8、s for this alclad reduction. Use of this product is not recommended without proper evaluation of corrosion resistance. 1.3 Application These products have been used typically for high strength parts requiring higher yield strength than is afforded by naturally aged tempers of this alloy and maximum

9、corrosion resistance and whose fabrication 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

10、 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 International
