13、yton, Ohio Foreword I This Standard is a revision of ANSI Standard H35.1/H35.1(M)-2006 Alloy and Temper Designation Systems for Aluminum. I Initially, the Standard consisted of only the alloy designation system for wrought aluminum developed by The Aluminum Association and adopted by that organizati
14、on in 1954. A booklet describing the system was issued in July 1954 and was approved under the existing standards procedure of the American Standards Association as American Standard H35.1- 1957. All major producers of wrought aluminum alloys in the United States adopted the Aluminum Association All
15、oy Designation System for Wrought Aluminum on October 1, 1954. A Military Standard (MIL-STD-192) covering the new system was issued in October 1955. The Society of Automotive Engineers began using the designations in 1956, and the American Society for Testing and Materials in 1958. The Standard was
16、reissued in 1962 to add the temper designation system that had been in effect in the United States since 1948. Subsequently, MIL-STD-192 was cancelled, since it was the equivalent to American Standard H35.1- 1962. This Standard was originally developed and subsequently revised using the “canvas“ met
17、hod and published under the proprietary sponsorship of the Aluminum Association. At the request of the Aluminum Association, the estab- lishment of Standards Committee H35 on Aluminum Alloys was authorized by the American National Standards Institute on 17 February 1970, with the Association serving
18、 as Secretariat. The 1971 revision of ANSI H35.1 was the first revision developed by Standards Committee H35, under the “Standards Committee“ procedures, and the 1972,1975, 1978, and 1982 revisions were developed under the auspices of that Committee. Standards Committee H35 was transferred to an Acc
19、redited Standards Committee on December 28, 1983, and this revision was developed under the Accredited Standards Committee method. This latest (2009) revision consists of modifications to clarify aluminum content for unalloyed aluminum made by a refining process, national variation composition limit
20、s, impurity limits for ingot and castings to which they apply. Additionally, definitions for T7 temper variations have been added and section headings have been editorially made more consistant. -,-,- I Alloy and Temper Designation Systems for Aluminum (ANSI H35.1-2009) 1 1. Scope This standard prov
21、ides systems for designating wrought aluminum and wrought aluminum alloys, aluminum and aluminum alloys in the form of castings and foundry ingot, and the tempers in which aluminum and aluminum alloy wrought products and aluminum alloy castings are produced. Specific limits for chemical compositions
22、 and for mechanical and physical properties to which conformance is required are provided by applicable product standards. NOTE: A numerical designation assigned in conformance with this standard should only be used to indicate an alu- minum or an aluminum alloy having chemical composition limits id
23、entical to those registered with The Aluminum Association and, for wrought aluminum and wrought alu- minum alloys, with the signatories of the Declaration of Accord on an International Alloy Designation System for Wrought Aluminum and Wrought Aluminum Alloys. 2. Wrought Aluminum and Aluminum Alloy D
24、esignation System A system of four-digit numerical designations is used to identify wrought aluminum and wrought aluminum alloys. The first digit indicates the alloy group as follows: Aluminum. 99.00 percent and greater. lxxx Aluminum alloys grouped by major alloying elementsB Copper . 2xxx Manganes
