ASTM F15-04

Standard Specification for Iron-Nickel-Cobalt Sealing Alloy

ABSTRACT
This specification covers an iron-nickel-cobalt alloy for use in sealing to glass in electronic applications. The alloy shall conform to the chemical composition specified and shall be manufactured in the form of wire, rod, bar, strip, sheet, and tube, with each form available in the specified temper condition. For example, tubes shall be bright annealed and supplied in the annealed temper condition. Strip and sheet shall be of temper A, B, C, D, or E or in deep-drawing temper condition, while wire and rod shall be bright annealed and supplied in temper A condition unless specified otherwise. The material shall be smooth, uniform in cross section, composition, and temper, and free of scale, corrosion, cracks, seams, scratches, slivers, and other defects. Tests for hardness, tensile strength, thermal expansion, and transformation shall be performed and shall conform to the requirements specified.
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 13 and 14 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.
