SAE AMS 7727E-2000 (SAE AMS7727E-2000)
Iron-Nickel-Cobalt Alloy, Bars and Forgings, 53Fe 29Ni 17Co Low Expansion, Glass Sealing ( Noncurrent: May 2006 )
This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of May 2006. It is recommended, therefore, that this specification not be specified for new designs. This specification covers an iron-nickel-cobalt alloy in the form of bars and forgings. Those products have been used typically for electronic elements to be sealed to hard glasses during assembly, but usage is not limited to such applications.
