Standard Specification for Aluminum-Alloy Sand Castings
|Publication Date:||1 September 2005|
|ICS Code (Aluminium products):||77.150.10|
1.1 This specification covers aluminum-alloy sand castings designated as shown in .
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 and H35.1M. Unified Numbering System alloy designations are in accordance with Practice E 527.
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 and .
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 non-conformance 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.

This specification covers aluminum alloy sand castings except those that are for aerospace applications. The chemical compositions are determined in accordance with the specified suitable chemical and spectrochemical test methods. Addition of small amounts of modifiers and grain refining elements to the molten alloys from the remelting furnace is permitted before casting. Pure metals, recycled materials, and master alloys can also be used to make the alloys as long as the chemical composition can be analyzed and adjusted to conform to the requirements prior to pouring any casting. Castings should only be repaired using approved processes such as welding, impregnation, peening, blending, soldering, and so forth.View Less
