1.1 This specification covers aluminum-alloy centrifugal castings designated as shown in Table 1.

1.2 This specification is not intended for aluminum-alloy centrifugal castings used in aerospace applications.

1.3 Alloy and temper designations are in accordance with ANSI H35.1 / H35.1 (M). The equivalent unified numbering system alloy designations are in accordance with Practice E527.

1.4 Unless the order specifies the "M" specification designation, the material shall be furnished to the inch-pound units.

1.5 For acceptance criteria for inclusion of new aluminum and aluminum alloys and their properties in this specification, see Annex A1 and Annex A2.

1.6 Units - 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.
