This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of November, 2005. 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. Similar but not necessarily identical processes are covered in the following specification. However, this listing is provided for information only and does not constitute authority to substitute these specifications for the noncurrent specification: AMS 5075; AMS 5077
