This specification covers an aluminum alloy in the form of alclad sheet and plate supplied in the –T3/-T351 temper.
Requirements for thin gage sheet (0.008 to 0.187 inch) in accordance with AMS4041 are superseded by AMS4462. AMS-QQ-A-250/5 and AMS4462 have the same requirements for alclad thickness and tensile properties for material less than 0.187" in thickness.
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 properties for this alclad reduction. Use of this product is not recommended without proper evaluation of corrosion resistance.
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 corrosion resistance and whose fabrication does not involve welding, but usage is not limited to such applications.
