Standard Specification for High-Strength, High-Conductivity Copper-Alloy Wire for Electronic Application

2017-09-06 /Active

This specification covers high-strength, high conductivity round copper-alloy wire used for electronic hook-up wire. The wires shall conform to the required minimum breaking strength and elongation. Electrical resistance and diameter of the wire shall be measured. The finished material shall be free of defects that detract from the normal end use or longevity of the product. Joints necessary to processing shall be of such quality that all requirements are met.


1.1 This specification covers high-strength, high-conductivity round copper-alloy wire 0.00099 to 0.0720 in. [0.025 to 1.829 mm] in diameter, used for electronic hookup wire. The tensile strength of the wire is 60 ksi [414 MPa] minimum and the electrical conductivity at 20°C is 85 % IACS minimum.

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 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, health and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
