(Specification)Standard Specification for Copper-Nickel-Zinc (Nickel Silver) Wire and Copper-Nickel Alloy Wire
Standard Specification for Copper-Nickel-Zinc (Nickel Silver) Wire and Copper-Nickel Alloy Wire
ABSTRACT
This specification establishes the requirements for wire in round, hexagonal, octagonal, rectangular, and square form of UNS Alloy Nos. C71000, C74500, C75200, C75700, C76400, C77000, and C79200. The chemical composition, temper, annealed wire grain size, tensile strength, and bending requirements are detailed.
SCOPE
1.1 This specification establishes the requirements for wire in round, hexagonal, octagonal, rectangular, and square form of UNS Alloy Nos. C71000, C74500, C75200, C75700, C76400, C77000, and C79200.
1.2 This specification is general in that the product is used in many applications where the requirements are too particular to be specified by standard test results.
1.2.1 For particular or critical applications it is advisable for the purchaser to submit samples or drawings to the manufacturer to secure an adjustment of anneal or temper to suit the application for which the product is intended.
1.3 The following information is intended to assist the purchaser in the application of this specification:
1.3.1 For most general applications—UNS Alloy Nos. C71000, C74500, C75200, and C75700.
1.3.2 For hard or spring tempers—UNS Alloy Nos. C76400 and C77000.
1.3.3 For ease of machining—UNS Alloy No. C79200.
1.4 Units—Values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
