ASTM B122/B122M-95

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

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: PreviouslyCopper AlloyUsed Nominal Composition, %UNS No.DesignationCopperNickel ZincTinChro-mium C70600...9010 .........C70620...8610 .........C7100068020 .........C7150057030 .........C71520...6531 .........C72200...8515 ......0.5C72500...899 ...2...C7350017218 10......C7400097010 20......C7450036510 24......C7520026518 17......C7620085912 29......C7700045518 27......Note 1--Plates of copper-nickel alloy Copper Alloy UNS Nos.

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.
