Standard Specification for
Aluminum-Alloy Sand Castings
1. Scope
1.1 This specification covers aluminum-alloy sand castings
designated as shown in Table 1.
1.2 This specification is not intended for aluminum-alloy
sand castings used in aerospace applications.
1.3 Alloy and temper designations are in accordance with
ANSI H35.1/H35.1M. 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 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 nonconformance
with the standard.
1.7 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.
