This specification covers an aluminum alloy in the form of plate 0.250 to 3.000 inches (6.35 to 76.20 mm) in nominal thickness (see 8.5). This plate has been used typically for parts requiring a high level of mechanical properties and resistance to exfoliation corrosion and moderate resistance to stress-corrosion cracking, but usage is not limited to such applications.
Rationale: AMS4201H 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.
