Initially, the Standard consisted of only the alloy designation system for wrought aluminum devel-oped by The Aluminum Association and adopted by … First, it is important to know 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. This Standard is a revision of ANSI Standard H35.1/H35.1(M)-2009 Alloy and Temper Designation Systems for Aluminum. Temper Designation System This system defines the sequence of basic treatments used to achieve the various tempers. 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. Aluminum Alloy Heat Treatment Temper 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. 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. – O (annealed): used for wrought or cast products made by some shaping process such as rolling, extrusion, forging, drawing, or casting, and which product at some point in the process has been annealed, used to achieve the lowest-strength condition, maximize subsequent workability or increase toughness and ductility. The Aluminum Association created the nomenclature and it is the organization that maintains the designation system. The system for designating heat treatment for forgings is the standard temper designation system for cast and wrought alloys. Slide 1 of 1 The specification of aluminum alloy can be broken down by its series, temper, and conditions. 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. CHAPTER 2: Aluminum Alloy and Temper Designation Systems of the Aluminum Association .....9 Wrought Aluminum Alloy Designation System . A four-digit numerical designation system is used to identify wrought aluminum and aluminum alloys. 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. 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. 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 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 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. T10 is cooled from an elevated temperature shaping process, artificially aged, and then cold worked. 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. used as key references, notably on the alloy and temper designation system and aluminum terminology, were the following: O Aluminum Standards and Data O Standards for Aluminum Sand and Permanent Mold Castings O Aluminum: Technology, Applications, and Environment 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. Wrought and cast aluminum designations are treated in a similar fashion. 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. - "International Temper Designation Systems for Wrought Aluminum Alloys : Part I – Strain Hardenable ( H Temper ) 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.
