Cast Aluminum. The most common T temper of aluminum is 6061-T6, it has been treated to provide the maximum precipitation hardening and therefore maximum yield strength. The secretariat to the noted specification is the “American Aluminum Association1” A system of letters and numbers known as the temper designation system is used to indicate the type of temper performed on an aluminium alloy. What is the difference between T6 and T651? T651 suitable for a thick plate, rolled or cold-finished bar and die forging, forging ring or rolling ring after solution heat treatment or cooling from high temperature forming process, these products are no longer straightened after stretching. Most alloys in the -W and -T4 conditions artificially aged to -T6. The heat treatment (temper) designation system of EN 515is used for all forms of wrought aluminium and aluminium alloys. T1 is cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition. This discussion expands on the . In addition to alloying elements, the temper also affects the properties of metals. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4.0–13%) contribute to give good casting characteristics.

T4 is solution heat treated and naturally aged to a substantially stable condition. A joint ANSI H35.1, EN 515, and ISO 2107 technical committee on a unified temper designation system has been established and meets periodically. This Standard is a revision of ANSI Standard H35.1/H35.1(M)-2013 Alloy and Temper Designation Systems for Aluminum. T9 is solution heat-treated, artificially aged, and then cold worked. The Aluminum Association created the nomenclature and it is the organization that maintains the designation system. c^/bŽ)¬Pˆ¹€Åî nƒ‹b±m¡‰'T¬T–­LÛVõ&'°]a“e+3,1ñN_wr¶PÖRsUŸÆf^¡›¯7¥•(âäóʚÖÜ¥sبeæF7™&çI³–.x4PwÞn5²q?7º9ÂÒv¢è2ÜÏM{[¯Ûl¹Á%È×\ ÅF29ù‡žª™È:=qªß±?z@OñnôúÈUåŠcêÔà6 á9 pæ;m[vh²)Pe §© XPȈ,“yôém ÎӀæCÌNØ|9*á†[Bm„º|!Ø@•O .Än¸+ȑ@g\jg„ Â. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc.There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. T7 is solution heat-treated and then stabilized. Processes used to produce aluminum alloy products are described briefly, and representative … The temper designation system is used for all forms of wrought and cast aluminum and aluminum alloys except ingots and is simply an extension of their alloy numbering system, which consists of a series of letters and numbers (Fig. The temper designation follows the alloy designation, the two being separated by a hyphen. This consists of a series of letters and numbers following the alloy designation number and connected by a hyphen. Temper Designation System This system defines the sequence of basic treatments used to achieve the various tempers. cold working, hot working) and thermal treatment (e.g. Temper Designation System This lettering and number system describes the thermo-mechanical treatment which has been applied to a particular alloy to achieve its mechanical properties. Aluminum Alloy Temper and Designation System In North America the Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. Aluminum Alloy Heat Treatment Temper Designations. Page 17 - Applies to products that have their strength increased by strain hardening, with or without supplementary thermal treatments to produce some reduction in strength. The temper designation follows the alloy designation and is separated from it by a hyphen. Initially, the Standard consisted of only the alloy designation system for wrought aluminum developed by Basic temper designations per ANSI H35.1/H35.1(M)-2009 and ad-opted by the European EN 515 and ISO 2107 temper designation systems. The Aluminum Association Technical Committee on Product Standards fixed this one by changing the temper to -01 designation. First, it is important to know The temper designation system is used for both wrought and cast aluminum alloys. Currently there are over 400 wrought aluminum and wrought aluminum alloys and over 200 aluminum alloys in the form of castings and ingots registered with the Aluminum Association. The temper designation follows the alloy designation, the two being separated by a dash. The Aluminum Alloy Temper and Designation System - In North America, The Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. The Aluminum Alloy Temper and Designation System - In North America, The Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. This designation follows the alloy designation; for example 5182-H18 refers to the alloy 5182 which has been strain hardened to increase the UTS by 90MPa. Alloy and Temper Designation Systems for Aluminum(STABILIZED Jan 2018) J993_201801 This standard provides 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. Though alloy nomenclature system for magnesium alloys varies in different regions across the globe, temper designation system is very similar to that of aluminum alloys. Aluminum Temper Designations TEMPER DESIGNATION SYSTEM The temper designation follows the alloy designation and is separated from it by a hyphen.The basic temper designations and subdivisions are as follows: 1-0 It recognizes more than 600 aluminum alloys—more than 400 wrought and more than 200 in the form of castings and ingots. This Standard is a revision of ANSI Standard H35.1/H35.1(M)-2013 Alloy and Temper Designation Systems for Aluminum. Property (mechanical or physical) limits apply to individual alloy-temper-product combinations. Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. Table II. Basic Aluminum Heat Treatment Designations In the production process of aluminum plate, due to heating and extrusion, the density between crystals is uneven, the energy can not be completely released, which is accumulated in the aluminum plate. A booklet describing the system was issued in July Temper is defined as the forging treatment (e.g. The Aluminum Temper Designation System. The temper designation refers to the hyphenated suffix to the basic alloy number, such as the -T651 in 6061-T651. Currently there are over 400 wrought aluminum and wrought aluminum alloys and over 200 aluminum alloys in the form of castings and ingots registered with the Aluminum Association. – T (thermally treated): thermally treated to produce stable tempers other than F, O, or H, products that are thermally treated will be designated with a -T temper, whether it is supplementary with or without strain-hardening, the digit after the T means specific thermal treatment. To get more detailed material property information, please see our Aluminum database or charts. . In this article, we’ll discuss the aluminum temper designation system and explain different tempers of aluminum alloy. Most F temper products are “semifinished” products. aluminum alloys temper designations . The difference in the -T6 and the -T651 or -T6510 or -T6511 tempers only shows when machining them: the stress-relieved tempers might be more stable. T8 is solution heat treated, cold worked, and then artificially aged. The basic temper designation consists of a letter. The first character in the temper designation, such as the T, indicates the type of treatment, the digit followed with the capital letter also reflects the operation type and order. In addition to providing a detailed account of the temper designation system for aluminum and aluminum alloys, this Article describes wrought and cast aluminum and aluminum alloy designations. Aluminum Temper Designations File Size: 30 kb File Type: pdf Download File Back TEMPER DESIGNATION SYSTEM The temper designation follows the alloy designation and is separated from it by a hyphen. 1) that follow the alloy designation number being separated by a hyphen (e.g., 6061-T6). Fortunately, great progress is being made in improving that situation, and the Aluminum Association’s alloy designation system is Designation of temper is necessary for right selection of aluminum alloys, properties of which depend not only on their compositions but also on the heat treatment of the alloys and the cold work of the parts. Is aluminum 6061 T6 the same as 6061 T6511? For example, 1060 aluminum would have a minimum pure aluminum content of 99.60%.
