1.1 This specification covers requirements for copper-nickel alloy castings whose nominal compositions are shown in Table 1. These are as follows:
|Copper Alloy UNS No.||Previous Designation|
1.2 Castings of these alloys are used primarily for corrosion-resisting purposes in both constructional and pressure applications and particularly in marine pumps, valves, and fittings.
1.3 These alloys are considered weldable, but they may be ordered with a weld test to ensure weldability. When extensive welding is to be performed on the casting, weldability tests should be specified in the ordering information (4.2.6) to ensure proper welding characteristics.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.5 This hazard statement applies only to Section 6, Weldability Test, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
