Standard Specification for Copper-Nickel-Tin Alloy, Copper-Nickel-Zinc Alloy (Nickel Silver), and Copper-Nickel Alloy Plate, Sheet, Strip, and Rolled Bar
ABSTRACT
This specification establishes the requirements for copper-nickel-tin, copper-nickel-zinc, and copper-nickel alloy plates, sheets, strips, and rolled bars made from UNS C70600, C70620, C71000, C71500, C71520, C72200, C72500, C73500, C74000, C74500, C75200, C76200, or C77000 alloy. Each product should be manufactured by hot or cold working, and annealed if required, to produce a uniform wrought structure that meets the specified temper properties. This specification also contains information on the standard tempers for and tensile strengths of hot-rolled, cold-rolled, and annealed tempers. In case of disagreements, the chemical composition is determined following appropriate methods listed here. Grain size is the standard requirement for all products in the annealed tempers.
SCOPE
1.1 This specification establishes the requirements for copper-nickel-tin alloy, copper-nickel-zinc alloy (nickel silver), and copper-nickel alloy plate, sheet, strip, and rolled bar. The following alloys are covered:

Note 1—Plates of copper-nickel alloy Copper Alloy UNS Nos. C70600, C70620, C71500, C71520, and C72200 for use as tube plates in surface condensers and heat exchangers are covered by Specification B 171/B 171M.
1.2 The values stated in either inch-pound units of SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.2.1 When the product is ordered in inch-pound units, the inch-pound units are to be regarded as the standard except grain size is always specified in millimetres.
1.2.2 When the product is ordered in SI units, the SI units are to be regarded as the standard.
