This specification covers an aluminum alloy in the form of coiled sheet 0.010 to 0.249 inch (0.25 to 6.32 mm), inclusive, in thickness, supplied in the -T4 temper (see 8.5).
Rationale:
AMS4477B results from a Five-Year Review and update of this specification with changes to correct elongation headings to show 50.8 mm (Tables 2B, 3B, and 4B), relocate the note regarding properties (3.3.5), update wording to prohibit unauthorized exceptions (3.3.4, 3.7, and 8.4), relocate definitions (2.4), update applicable documents (Section 2), and allow the use of the immediate prior specification revision (8.3).
