    Abstract

    This specification covers commercial aluminum alloys in ingot form for remelting and molten form for the manufacture of castings. The material shall be of uniform quality and shall be free from dross, slag, and other harmful contamination. The ingots or molten metal shall conform to the chemical composition limits specified.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers commercial aluminum alloys in ingot form for remelting and molten form for the manufacture of castings. The specific gravity of these alloys does not exceed 3.0 and they are designated as shown in Table 1.

    Note 1: Throughout this specification the use of “ingot” in a general sense includes sow, T-bar, T-ingot, and pig.

    1.2 Alloy designations are in accordance with ANSI H35.1/H35.1(M).

    Note 2: Supplementary data pertaining to the alloys covered by this specification when used in the form of castings are given in Specifications B26/B26M, B85/B85M, B108/B108M, B618/B618M, B686/B686M, B955/B955M, and B969/B969M.

    1.3 Unless the order specifies the “M” specification designation, the material shall be furnished to the inch-pound units.

    1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A1.

    1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

    1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
