5、h The Aluminum Association but not contained in The Associations Aluminum Standards and Data Metric SI.This is the fourth publication of the registration record of “Tempers for Aluminum and Aluminum Alloy Products-Metric Edition”. For most parts the method of preparation has been to arrive at logica
6、l metric values rather than to restate current inch-pound values in metric terms by use of conversion factors. The metric units in this publication are based on the International System of Units (SI). The strength properties are expressed in megapascals (MPa). Refer to APPENDIX A, “Guidlines for Har
7、d Conversion of U.S. Customary Units to Sl (Metric) Units”, for specific conversion procedures and to the Yellow Sheets (Tempers for Aluminum and Aluminum Alloy Products) for registered tempers with limits shown in customary units from which some metric units are derived for this document.Some of th
8、e 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 pages 1-32 and for castings on page 33. Inactive alloys and tempe
9、rs are listed on pages 37-44.An explanation for The Aluminum Associations “Temper Designation System” is given in the Aluminum Standards and DataMetric SI and in the American National Standard ANSI H35.1/H35.1(M).All new tempers registered since the previous issue as well as revisions to the prior r
10、egistra-tions 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 produced in a temper not previously applied to that matr
11、ial, 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 Association to register a new temper.2. Selection of th
12、e 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 the Technical Committee on Product Standards, it is judge
13、d to be technically correct and complete with respect to the following:3.a. The temper designation conforms to ANSI H35.1(M) “Alloy and Temper Designation Systems for Aluminum” (reprinted in The Aluminum Association manual Aluminum Standards and Data Metric SI).3.b. The material is offered for sale
14、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 “Mechanical Properties” in Section 6, “Standards
15、 Section” of Aluminum Standards and Data Metric SI).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 treatment, rolling mill solution
16、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 heat treated material. No more than
17、 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 Metric SI Section 1, Alloy and Temper Designation System for Aluminum (ANSI H35.1(M), Paragraph 4.2.2, for the tem
18、per 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 557M. Statistically analyze the data for Ultimate Tensile Strength, Yield Strength, and Elongation, and report the minimum values for each
19、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 diameter and, if appro
20、priate, 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 extrud-ed, rolled or forged and solution heat treated in a production or commercial furnace.
21、 Stretch, cold work, straighten or otherwise finish the material as described in Aluminum Standards and Data Metric SI Section 1, Alloy and Temper Designation System for Aluminum (ANSI H35.1 (M), Paragraph 4.2.2, for the temper being registered. Then either naturally age (T3 and T4) or artificially
22、age (T6, T7, T8, and T9) the material before sampling and tensile testing per ASTM B 557M. 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 con
23、fidence 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 wishes
24、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. Temper
25、s 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 t
26、emporary 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 tentativ
27、e 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 distri-bution that is expected due to random variation within the manufacturing practice and may
28、 not have a normal distribution.3.c.2.3. For heat treatable alloys, tentative limits are based on the results of a minimum of 30 tests from at least 3 cast lots and at least 3 heat treat lots of material. For non heat treatable alloys, tentative limits are based on the results of a minimum of 30 tes
29、ts from at least 3 cast lots of material that have separately passed through subsequent pro-cessing operations as at least 3 fabricated inspection lots.3.c.2.4. For heat treatable and non heat treatable alloys, the 30 tests shall include observa-tions from all gauge ranges. Multiple ranges can be pr
30、oposed when there are at least 10 tests from each gauge range or by using regression analysis of the 30 tests.3.c.2.5. Tentative limits for 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 treatme
31、nt, rolling mill solution heat treatment or forging press solution heat treat-ment (see 3.c.1.), are based on the results of a minimum of 30 tests from at least 3 cast lots and at least 3 heat treat lots of material processed as described in 3.c.1.1. and a minimum of 30 tests from at least 3 cast lo
32、ts and at least 3 heat treat lots of material processed as described in 3.c.1.2.3.c.2.5.1. The 30 tests from the material processed as described in 3.c.1.1. shall in-clude samples which span the thickness range(s) to be registered, including samples from the thinnest section or diameter, the thickes
33、t section or diam-eter and, if appropriate, intermediate sections or diameters. There shall be a minimum of 10 tests for each thickness range to be registered. 3.c.2.5.2. The 30 tests from material processed as described in 3.c.1.2. may be from one or multiple gauge thickness.TEMPER REGISTRATION (co
34、ntinued)ivJuly, 20113.d. The following additional information is included when characteristics, in addition to mechanical prop-erties, are specified for the temper: 3.d.1. Test methods by which conformance with the requirements for specified characteristics can be evaluated, OR3.d.2. Details of the
35、practice to be followed in producing the temper.3.e. When not already registered, the minimum tensile strength limit applicable to the O temper shall ac-company the request for registration of H tempers.3.e.1. If the annealed product is not offered for sale and the O temper limits that accompany an
36、H temper registration are based on material annealed in standard production furnaces, the de-scription provided in the Remarks column of the registration shall state “O temper not offered for sale but used as basis for H temper registration.”3.e.2. If the annealed product is not offered for sale, th
37、e O temper limits can be measured on labora-tory annealed materials. These limits shall be designated as O2 and the description provided in the Remarks column of the registration shall state “O temper not offered for sale. O2 temper used as basis for H temper registration.”3.e.3. When the O temper o
38、r O2 temper limits are based on the requirements of a tentative registra-tion, the O or O2 limits will be shown as tentative. However, O or O2 temper tentative limits, which are noted as not being offered for sale, shall not be subject to the two year review.3.f. The indication of a variation in tre
39、atment of a basic T temper is limited to one additional digit (exclud-ing zero) unless all available digits have been used, and except as provided for in the Appendix to ANSI H35.1(M). 3.g. A description of the process variation or the product characteristics of the registration shall be pro-vided w
40、hen an additional digit, beyond those defined, is requested.TEMPER REGISTRATION (continued)vJuly, 2011PROCEDURES FOR ALUMINUM ASSOCIATION TECHNICAL DIVISION (AATD) REGISTRATION OF TEMPERSA temper for an aluminum alloy material may be registered as an AATD temper when, through formal ballot of the Te
