Product Code:SAE AMS4125
Title:Aluminum Alloy Die Forgings, and Rolled or Forged Rings, 0.90Si - 0.62Mg - 0.25Cr, (6151-T6) Solution and Precipitation Heat Treated (NONCURRENT Aug 2009)
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of August 2009. It is recommended, therefore, that this specification not be specified for new designs.“NONCURRENT” refers to those materials which may have been widely used previously 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.“NONCURRENT” specifications are available from SAE upon request.
