適用范圍：This specification covers an aluminum alloy in the form of plate. This plate has been used typically for aerospace structural parts requiring strength similar to that of 7075-T651 but having 7.8% lower nominal density, but usage is not limited to such applications. This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of April 2007. It is recommended, therefore, that this specification not be specified for new designs. NONCURRENT refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs.
