This specification covers electronic grade alloys of copper and nickel in wrought forms suitable for external and internal use in electron devices. The alloy shall be free from directional properties and shall be handled in such a manner that oxide contamination is minimized. The material shall conform to the chemical composition requirements which include nickel, cobalt, iron, zinc, manganese, lead, carbon, silicon, sulfur, aluminum, phosphorus, and copper contents. Grain size, mechanical properties, and magnetic permeability shall conform to the requirements of this specification. The alloys shall be tested for macroscopical and microscopical examinations. Packaging and marking shall be in accordance to this specification.

1.1 This specification covers alloys of copper and nickel in a variety of wrought shapes suitable for external and internal use in electron devices.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 The following safety hazards caveat applies to Test Methods Section 8 only: 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.
