SCOPE: 1.1 Form: This sp
6、ecification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing. 1.2 Application: These products have been used typically for parts subject to excessive warpage during machining, and for parts requiring high strength and whose fabrication does not normally involve
7、 welding, but usage is not limited to such applications. 1.2.1 Certain design and processing procedures may cause these extrusions to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions. 2. APPLICABLE DOCUMENTS: The issue of the following document
8、s in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has
9、 been specified, the last published issue of that document shall apply.

Purchaser reserves the right to sample and to perform any conf
26、irmatory testing deemed necessary to ensure that the extrusions conform to specified requirements. 4.2 Classification of Tests: Composition (3.1), tensile properties (3.3.1), ultrasonic inspection when specified (3.4.1), and tolerances (3.5) are acceptance tests and, except for composition, shall be

REJECTIONS: Extrusions not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. 8. NOTES: 8.1 A change bar (|) located in the left margin
32、 is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of a specification. An (R) symbol to the left of the document title indicates a complete revision of the specification, including technical revision. Change ba
33、rs and (R) are not used in original publications, nor in specifications that contain editorial changes only. 8.2 Hardness should be not lower than 100 HB/10/500 or 106 HB/10/1000, determined in accordance with ASTM E 10. Hardness has been used to verify that extrusions are properly processed, but an
34、 out-of-range hardness number is not always indicative of extrusions with out-of-specification tensile properties. Further analysis, including material composition verification, heat treat process parameter review, and/or tensile property measurement on extrusions with out-of-range hardness, may be
35、necessary. 8.3 Terms used in AMS are clarified in ARP1917. 8.4 Dimensions and properties in inch/pound units are primary; dimensions and properties in SI units are shown as the approximate equivalents of the primary units and are presented only for information. 8.5 Purchase documents should specify
36、not less than the following: AMS 4164H Form and size or section identification number of extrusions desired Quantity of extrusions desired Ultrasonic inspection report when specified (See 3.4.1). 8.6 Similar Specifications: AMS QQ-A-200/3, Temper T3510, is listed for information only and shall not be construed as an acceptable alternate unless all requirements of this AMS are met. 8.7 Key Words: Bars, rods, wire, profiles, tubing PREPARED UNDER THE JURISDICTION OF AMS COMMITTEE “D”
