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

SAE AMS 4992 is a similar, but not identical specification.

This specification covers a premium grade titanium alloy in the form of investment castings.

These castings have been used typically for parts of intricate design requiring a combination of good strength-to-weight ratio and corrosion resistance up to 550 \mDF (288 \mDC), but usage is not limited to such applications.
