This specification covers iron-nickel-chromium alloy (UNS K94760) used primarily for glass-sealing applications in electronic devices. The chemical composition of the material shall conform to the requirements prescribed. Chemical analysis shall be made, when desired, in accordance with the prescribed requirements. The average linear coefficient of thermal expansion shall be within limits of the requirements specified. The material shall be commercially smooth, uniform in cross section, in composition, and in temper; it shall be free of scale, corrosion, cracks, seams, scratches, slivers, and other defects.

1.1 This specification covers two iron-nickel-chromium alloys (UNS K94760 and UNS K95150) used primarily for glass-sealing applications in electronic devices.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 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.
