Standard Specification for Copper-Nickel-Tin Alloy, Copper-Nickel-Zinc Alloy (Nickel Silver), and Copper-Nickel Alloy Plate, Sheet, Strip, and Rolled Bar

This specification covers 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: Previously Copper Alloy Used Nominal Composition, UNS No. 2 Designation % Chro- Copper Nickel Zinc Tin mium C70600 90 10 C71000 6 80 20 C71500 5 70 30 C72200 85 15 0.5 C72500 89 9 2 C73500 1 72 18 10 C74000 9 70 10 20 C74500 3 65 10 24 C75200 2 65 18 17 C76200 8 59 12 29 C77000 4 55 18 27 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 in 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 millimeters. 1.2.2 When the product is ordered in SI units, the SI units are to be regarded as the standard.
