1、Designation: F 30 96 (Reapproved 2002)Standard Specification forIron-Nickel Sealing Alloys1This standard is issued under the fixed designation F 30; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A numbe
2、r in parentheses indicates the year of last reapproval. A superscriptepsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers iron-nickel alloys that areintended primarily for sealing to glass in electronic applica-tions.NOTE 1Some of thes
3、e alloys may be used for sealing to ceramics, butthis specification in its present form is not intended to cover material formetal-to-ceramic seals.1.2 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.3 This standard d
