(Specification)Standard Specification for Aluminum-Alloy Castings Produced by Squeeze Casting, Thixocast and Rheocast Semi-Solid Casting Processes
Standard Specification for Aluminum-Alloy Castings Produced by Squeeze Casting, Thixocast and Rheocast Semi-Solid Casting Processes
SCOPE
1.1 This specification covers aluminum-alloy castings, produced by the thixocast, rheocast, semi-solid, and squeeze casting processes shown in Table 1. (A) When single units are shown, they indicate the maximum amounts permitted.(B) Analysis shall be made for the elements for which limits are shown in this table.(C) The following applies to all specified limits in this table: For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit in accordance with the rounding-off method of Practice E29.(D) In case of discrepancy between the values listed in Table 1 and those listed in the “Designations and Composition Limits for Aluminum Alloys in the Form of Castings and Ingot (known as the “Pink Sheets”)”, the composition limits registered with the Aluminum Association and published in the “Pink Sheets” shall be considered the controlling composition.(E) “Others” includes listed elements for which no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements not specified in the specification. However, such analysis is not required and may not cover all metallic “Others” elements. Should any analysis by the producer or the purchaser establish that an “Others” element exceeds the limit of “Each” or that the aggregate of several “Others” elements exceeds the limit of “Total,” the material shall be considered nonconforming.(F) Other Elements—Total shall be the sum of unspecified metallic elements 0.010 % or more, rounded to the second decimal before determining the sum.(G) If iron exceeds 0.45, manganese content shall not be less than one-half iron content.(H) The Aluminum Association ruling on the number of decimal places to which Mg percent is expressed is exempted for some long standing alloys. See A2.2.6.(I) For a cross reference of current and former alloy designations see the Aluminum Association’s “Designations and Chemical Composition Limits for Aluminum Alloys in the Form of Castings and Ingot (The Pink Sheets)”.
1.2 This specification is for aluminum-alloy squeeze castings, and semi-solid Thixocast and Rheocast castings used in general purpose applications. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
1.3 Alloy and temper designations are in accordance with ANSI H35.1/H35.1 (M).
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 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.
1.8 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.
