This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of October, 2003. It is recommended, therefore, that this specification not be specified for new designs. NONCURRENT refers to those materials which have previously been widely used and which may be required on some existing designs in the future. The Aerospace Materials Division, however, does not recommend these as standard materials for future use in new designs.

This specification covers an aluminum alloy powder metallurgy product in the form of sheet 0.010 to 0.250 inch (0.25 to 6.35 mm) in nominal thickness.

This sheet has been used typically for parts requiring good strength, but usage is not limited to such application.
