Historical Standard: ASTM F15-98 Standard Specification for Iron-Nickel-Cobalt Sealing Alloy
SUPERSEDED (see Active link, below)
ASTM F15
1. Scope
1.1 This specification covers an iron-nickel-cobalt alloy, UNS K94610 containing nominally 29% nickel, 17% cobalt, and 53% iron, in the forms of wire, rod, bar, strip, sheet, and tubing, intended primarily for sealing to glass in electronic applications.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following hazard caveat pertains only to the test method portion, Sections 14 and 15 of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
