Aluminum Alloy, Alclad Sheet (6156-T4) 1.0Si - 0.90Cu - 0.60Mn - 0.90Mg Solution Heat Treated and Naturally Aged (Composition similar to UNS AA6156)
AMS4405
1.1 Form
This specification covers an aluminum alloy procured in the form of sheet 0.078 to 0.197 inch (2.00 to 5.00 mm), inclusive, in nominal thickness, Alclad on both sides (see 8.5).
1.2 Application
These products have been used typically for formed structural parts requiring good formability in T4 temper and ability to develop improved resistance to fatigue crack growth and high toughness with moderate strength when aged to T62 temper, but usage is not limited to such applications.
Rationale: AMS4405D results from a Five-Year Review and update of this specification. This standard is being reviewed as part of the SAE Five-Year Review policy. The committee will look at possible changes to ordering information and other potential updates throughout the standard.
