Aluminum Alloy, Sheet and Plate, Alclad 4.4Cu - 1.5Mg - 0.60Mn (2024, -T3 Sheet/-T351 Plate with 1-1/2% Alclad) Solution Heat Treated, Cold Worked and Naturally Aged
|Publication Date:||1 September 2019|
This specification covers an aluminum alloy in the form of sheet and plate alclad two sides, over 0.187 to 1.000 inch (over 4.750 to 25.40 mm) in nominal thickness, supplied in the -T3/-T351 temper.
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.
Requirements for thin gage sheet (0.008 to 0.187 inch) in accordance with AMS4041 are superseded by AMS4462.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 inch in thickness.
These products have been used typically for high strength parts requiring higher yield strength than is afforded by non-cold worked, naturally aged tempers of this alloy, maximum corrosion resistance and fabrication that does not involve welding, but usage is not limited to such applications.
