【国外标准】 Standard Specification for Hard-Drawn Copper Alloy Wires for Electric Conductors (Withdrawn 2023)

This specification covers hard-drawn round copper alloy wires for electric conductors. The wires shall be made in any one of ten distinct alloys designated 8.5, 13, 15, 20, 30, 40, 55, 74, 80, and 85 in accordance with their increasing electrical conductivities. Specimens shall undergo tests to which they shall meet the required values for chemical composition, electrical resistivity, and mechanical and physical properties. The mechanical properties to be examined are elongation and tensile strength, while the physical properties in consideration are wire diameter, area, and density. The completed wire, to which no joints are to be made, shall be free from all imperfections not consistent with the best commercial practice.1.1 This specification covers hard-drawn round copper alloy wires for electric conductors.1.2 The copper alloy wires shall be made in any one of ten distinct alloys designated 8.5 to 85 in accordance with their increasing conductivities or designated by assigned UNS numbers (see Explanatory Note 1) as follows:  Copper Alloy UNSNo.   Copper Alloy UNSNo. Alloy 8.5 C65100 Alloy 40  Alloy 13 C51000 Alloy 55 C16500Alloy 15   Alloy 74 C19600Alloy 20   Alloy 80 C16200Alloy 30 C50700 Alloy 85 C162001.3 The values stated in inch-pound units are to be regarded as standard.
