1.1 This specification establishes requirements for centrifugal castings of copper-base alloys having the nominal compositions shown in Table 1. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard. TABLE 1 Nominal Compositions | Classification | Copper Alloy
