2、ormationThe Aluminum Association has used its best efforts in compiling the information contained in this publication. Although the Association believes that its compilation procedures are reliable, it does not warrant, either expressly or impliedly, the accuracy or completeness of this information.
3、 The Aluminum Association assumes no responsibility or liability for the use of the information herein. All Aluminum Association published standards, data, specifications and other material are reviewed at least every five years and revised, reaffirmed or withdrawn. Users are advised to contact The
4、Aluminum Association to ascertain whether the information in this publication has been superseded in the interim between publication and proposed use.iJuly, 2011FOREWORDListed in this booklet are the tempers for aluminum and aluminum alloy products registered with The Aluminum Association but not co
5、ntained in The Associations Aluminum Standards and Data.Some of the registered tempers may be the subject of U.S. patents or patent applications, and their listing herein is not to be construed in any way as the granting of a license under such patent rights.Tempers for wrought products are given on
6、 pages 130 and for castings on page 31. Inactive alloys and tempers are listed on pages 3441.An explanation for The Aluminum Associations “Temper Designation System” is given in the Aluminum Standards and Data and in the American National Standard ANSI H35.1/H35.1(M).All new tempers registered since
7、 the previous issue as well as revisions to the prior registrations are marked and defined. In addition, the registration column also includes a revision date to denote the latest revision to the registered information.iiJuly, 2011TEMPER REGISTRATIONWhen any aluminum or aluminum alloy material is pr
8、oduced in a temper not previously applied to that material, the temper, along with the alloy designation and product form to which it applies, may be registered with The Aluminum Association.PROCEDURE FOR INDIVIDUAL REGISTRATION OF TEMPERS1. Any person, firm or corporation may apply to The Aluminum
9、Association to register a new temper.2. Selection of the temper designation usually is left to the discretion of the Technical Committee on Product Standards, but consideration will be given to the applicants choice when circumstances so warrant.3. The temper is registered when, in the opinion of th
10、e Technical Committee on Product Standards, it is judged to be technically correct and complete with respect to the following:3.a. The temper designation conforms to ANSI H35.1 “Alloy and Temper Designation Systems for Aluminum” (reprinted in The Aluminum Association manual Aluminum Standards and Da
11、ta).3.b. The material is offered for sale in the proposed temper and is available for use by more than one user.3.c. The mechanical property limits applicable to the temper are included. (Limits are shown as tentative unless established in accordance with the data base criteria outlined under “Mecha
12、nical Properties” in Section 6, “Standards Section” of Aluminum Standards and Data).3.c.1. The following procedure describes a method to register 6xxx and some 7xxx in -T3, -T4, -T6, -T7, -T8 and -T9 Tempers, when the temper being registered is normally produced using extrusion press solution heat t
13、reatment, rolling mill solution heat treatment or forging press solution heat treatment.3.c.1.1. Collect 100 samples minimum from at least 5 different cast lots and 10 different heat treat lots of extrusion press solution heat treated, rolling mill solution heat treated or forging press solution hea
14、t treated material. No more than 10 tests from a given heat treat lot shall be included in the data analysis. Stretch, cold work, straighten or otherwise finish the material as described in Aluminum Standards and Data Section 1, Alloy and Temper Designation System for Aluminum (ANSI H35.1), Paragrap
15、h 4.2.2, for the temper being registered. Then either naturally age (T3 and T4) or artificially age (T6, T7, T8, and T9) the material before sampling and tensile testing per ASTM B 557. Statistically analyze the data for Ultimate Tensile Strength, Yield Strength, and Elongation, and report the minim
16、um values for each at which at least 99 percent of the material is expected to conform at a confidence level of 0.95.3.c.1.1.1. The 100 tests shall include samples which span the thickness range(s) to be registered, including samples from the thinnest section or diameter, the thickest section or dia
17、meter and, if appropriate, intermediate sections or diameters. There shall be a minimum of 30 tests for each thickness range to be registered.3.c.1.2. Collect 30 samples minimum from at least 3 different cast lots of material extruded, rolled or forged and solution heat treated in a production or co
18、mmercial furnace. Stretch, cold work, straighten or otherwise finish the material as described in Aluminum Standards and Data Section 1, Alloy and Temper Designation System for Aluminum (ANSI H35.1), Paragraph 4.2.2, for the temper being registered. Then either naturally age (T3 and T4) or artificia
19、lly age (T6, T7, T8, and T9) the material before sampling and tensile testing per ASTM B 557. Statistically analyze the data for Ultimate Tensile Strength, Yield Strength, and Elongation, and report the minimum values for each at which at least 99 percent of the material is expected to conform at a
20、confidence level of 0.95.iiiJuly, 20113.c.1.2.1. The 30 tests may include samples from one or multiple gauge thickness. 3.c.1.3. The registering entity shall report all calculated minimum values to the Technical Committee on Product Standards, along with the minimum limits the registering entity wis
21、hes to register.3.c.1.4. The Technical Committee on Product Standards will then review the temper based on the proposed minimum limits of the registering entity, provided the minimum limits are not larger than the minimum values calculated in steps 3.c.1.1 and 3.c.1.2 of this procedure.3.c.1.5. Temp
22、ers registered using this procedure shall carry the following note in the Remarks column: “The registered properties for this material are calculated in accordance with the procedure described under 3.c.1 on page ii of this document”. 3.c.2. Tentative Limit Registration3.c.2.1. Tentative limits are
23、temporary in nature and are established to allow the producer to manufacture and sell the product while continuing to collect data. Tentative temper designations shall be reviewed every 2 years for possible resolution of the tentative status.3.c.2.2. The mechanical property limits defined as tentati
24、ve are established at levels at which at least 99% of the data conform at a confidence level of 95%. The limited number of observations required for a tentative registration may not represent the property distribution that is expected due to random variation within the manufacturing practice and may
