1、Designation: B179 17B179 18Standard Specification forAluminum Alloys in Ingot and Molten Forms for Castingsfrom All Casting Processes1This standard is issued under the fixed designation B179; the number immediately following the designation indicates the year oforiginal adoption or, in the case of r
2、evision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This speci
3、fication covers commercial aluminum alloys in ingot form for remelting and molten form for the manufacture ofcastings. The specific gravity of these alloys does not exceed 3.0 and they are designated as shown in Table 1.NOTE 1Throughout this specification the use of “ingot” in a general sense includ
4、es sow, T-bar, T-ingot, and pig.1.2 Alloy designations are in accordance with ANSI H35.1/H35.1(M).NOTE 2Supplementary data pertaining to the alloys covered by this specification when used in the form of castings are given in SpecificationsB26/B26M, B85/B85M, B108/B108M, B618/B618M, B686/B686M, B955/
5、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
6、are to be regarded as standard. No other units of measurement are included in thisstandard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety, health, and envi
