1 . SCOPE:

1 .1 Form: This specification covers an aluminum alloy in the form of die'fOrgings, hand forgings, rolled ring forgings, and forging stock.

1.2 Application: Primarily for complex shaped parts requiring moderate strengthand good forgeability of the material. Corrosion resistance of this alloyis superior'to that of alloys having copper as the principal alloyingelement.

2. APPLICABLE DOCUMENTS: The following publications form a part of th:sspecification to the extent specified herein. The latest issue of AerospaceMaterial Specifications shall apply. The applicable issue of other documents

~.~.l~hall be as specified in AMS 2350.
