ANSI H35.1, 2004 Edition, 2004 - Alloy and Temper Designation Systems for Aluminum 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. The physical properties exhibited by aluminum alloys are significantly influenced by the treatment of the sample. The aluminum alloy data sheets in MatWeb will generally have a temper designation connected with them to indicate the treatment used to produce the properties listed. Aluminum Temper Designation System The wrought aluminum alloys are usually designated by a four-digit number, the first digit generally identifies the major alloying element, so the aluminum alloy family including 1xxx, 3xxx, and 5xxx series that are non-heat-treatable, 2xxx, 6xxx and 7xxx series are heat treatable, as well as the 4xxx series contain both alloys that can be heat-treated or … T6 and T651 are two -T tempers of aluminum alloy, common examples are aluminum 6061-T6 and 7075-T6. This Standard is a revision of ANSI Standard H35.1/H35.1(M)-2009 Alloy and Temper Designation Systems for Aluminum. Most F temper products are “semifinished” products. This energy is called internal stress. CHAPTER 2: Aluminum Alloy and Temper Designation Systems of the Aluminum Association .....9 Wrought Aluminum Alloy Designation System . Temper Designation System. 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 Temper Designation System: The temper designation system is used for all forms of wrought and cast aluminum and aluminum alloys. 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. It is based on the sequence of basic treatments used to produce various tempers. The temper designation system is used for all forms of wrought and cast aluminum and aluminum alloys except ingot. Basic temper designations consist of letters (F, O, H, W, T). The Aluminum Alloy Temper and Designation System In North America, The Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. each country around the world has its own designations system for aluminum alloys and tempers.

Aluminum Alloy Temper and Designation System In North America the Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. A standardized system has been developed to designate these treatments. Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. 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. T7 is solution heat-treated and then stabilized. The temper designation follows the alloy designation and is separated from it by a hyphen. ต อมาในป ค.ศ. – 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. 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. General Characteristics of Aluminum – Lightweight yet structural Fortunately, great progress is being made in improving that situation, and the Aluminum Association’s alloy designation system is 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. Most alloys in the -W and -T4 conditions artificially aged to -T6. Annotation Examines characteristics of wrought and cast aluminum alloys, then presents basic aluminum alloy and temper designation systems, as developed by the Aluminum Association, and explains them with examples. 3.2.4 Temper designation system for wrought alloys (EN 515) Basic Considerations The heat treatment (temper) designation system of EN 515 is used for all forms of wrought aluminium and aluminium alloys. Aluminum Temper Designations A descriptive nomenclature providing control to the designation to and the degree of temper applied to wrought aluminum and wrought aluminum alloys for both casted and foundry ingot is provided for by ANSI H35.1-2004. The temper designation follows the alloy designation, the two being separated by a hyphen. The Aluminum Association designation system is defined according to ANSI H35.1 with respect to the designation and composition of aluminum alloys and tempers registered in the United States, and is also harmonized through cold working, hot working) and thermal treatment (e.g. Four basic temper designations are used for 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. It is based on the sequences of basic treatments used to produce the various tempers. There are many different rules for labeling the various types of aluminum alloys. Temper Designation System This system defines the sequence of basic treatments used to achieve the various tempers. -T6511 is a subset of the -T6 temper with eliminated internal stress, so it’s more suitable for processing. Basic Aluminum Heat Treatment Designations Sub-divisions of the basic temper are indicated by The temper designation follows the alloy designation with the two separated by a hyphen. In reality, nothing is actually ever "used" in this temper condition, as it is just a convenient way to label or give a name to forgings in an intermediate stage of processing. The temper designation system is used for both wrought and cast aluminum alloys. Posted by Author on Monday 08 April 2019 Where used, the temper designation follows the alloy designation and is separated from it by a dash. Temper is defined as the forging treatment (e.g. Wrought and cast aluminum designations are treated in a similar fashion. Initially, the Standard consisted of only the alloy designation system for wrought aluminum devel- oped by The Aluminum Association and adopted by that organization in 1954. })(jQuery); Junying Metal Manufacturing has developed high-level manufacturing technique in T651: solution treatment + stress-relieve by stretching + artificially aging, for the precise workpiece, T651 should be selected in order to avoid elastic recovery after processing, and dimension stability can’t be maintained. The temper of an alloy can affect the appearance and mechanical properties of a product. Temper Designation System . Technical Info Temper Designation System. 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. There are five basic temper designations used for aluminum alloys, meaning different treatment or process.

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. Aluminum Alloy Heat Treatment Temper Designations. 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. The temper designation refers to the hyphenated suffix to the basic alloy number, such as the -T651 in 6061-T651. The temper designation follows the alloy designation with the two separated by … A four-digit numerical designation system is used to identify wrought aluminum and aluminum alloys. 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 system of letters and numbers known as the temper designation system is used to indicate the type of temper performed on an aluminium alloy. The temper designation follows four-digit Aluminium Alloy Designation, the two being separated by a hyphen. Instances like this showed the continuing need to standardize the temper designations and maintain discipline to the system according to some "rules". An aluminum temper designation is a series of letters and numbers that are used to denote what type of tempering treatment an aluminum alloy has undergone. 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. This discussion expands on the . The temper designation system addresses these material conditions through an extension of the alloy numbering system. 1) that follow the alloy designation number being separated by a hyphen (e.g., 6061-T6). Temper Designation System The temper designation system is used for all forms of wrought and cast aluminum and aluminum alloys except ingot. All these systems are covered by American National Standards Institute (ANSI) standard H35.1. 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. Examples: 6061-T6, 6063-T4, 5052-H32, 5083-H112. The Temper Designation System is an extension of the alloy numbering system and consists of a series of letters and numbers which follow the alloy designation number and are connected by a hyphen.
