Alloy and Temper Designation Systems for Aluminum and Aluminum Alloys
R.B.C. Cayless, Alcan Rolled Products Company
SYSTEMS FOR DESIGNATING aluminum and aluminum alloys that incorporate the product form (wrought, casting, or foundry ingot), and its respective temper (with the exception of foundry ingots, which have no temper classification) are covered by American National Standards Institute (ANSI) standard H35.1. The Aluminum Association is the registrar under ANSI H35.1 with respect to the designation and composition of aluminum alloys and tempers registered in the United States.
Wrought Aluminum and Aluminum Alloy Designation System
A four-digit numerical designation system is used to identify wrought aluminum and aluminum alloys. As shown below, the first digit of the four-digit designation indicates the group:
Aluminum, ->99.00%.............................. lxxx Aluminumalloysgrouped by major alloying
element(s): Copper. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2xxx Manganese. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3xxx Silicon. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4xxx Magnesium . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5xxx Magnesiumand silicon ......................... 6xxx Zinc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7xxx Other elements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8xxx Unused series. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9xxx
For the 2xxx through 7xxx series, the alloy group is determined by the alloying element present in the greatest mean percentage. An exception is the 6xxx series alloys in which the proportions of magnesium and silicon available to form magnesium silicide (MgzSi) are predominant. Another exception is made in those cases in which the alloy qualifies as a modification of a previously registered alloy. If the great-
est mean percentage is the same for more than one element, the choice of group is in order of group sequence: copper, manganese, silicon, magnesium, magnesium silicide, zinc, or others.
Aluminum. In the lxxx group, the series
lOxx is used to designate unalloyed compositions that have natural impurity limits. The last two of the four digits in the designation indicate the minimum aluminum percentage. These digits are the same as the two digits to the right of the decimal point in the minimum aluminum percentage when expressed to the nearest 0.01%. Designations having second digits other than zero (integers 1 through 9, assigned consecutively as needed) indicate special control of one or more individual impurities.
Aluminum Alloys. In the 2xxx through
8xxx alloy groups, the second digit in the designation indicates alloy modification. If the second digit is zero, it indicates the original alloy; integers 1 through 9, assigned consecutively, indicate modifications of the original alloy. Explicit rules have been established for determining whether a proposed composition is merely a modification of a previously registered alloy or if it is an entirely new alloy. The last two of the four digits in the 2xxx through 8xxx groups have no special significance, but serve only to identify the different aluminum alloys in the group.
Cast Aluminum and Aluminum Alloy Designation System
A system of four-digit numerical designations incorporating a decimal point is used to identify aluminum and aluminum alloys in the form of castings and foundry ingot. The first digit indicates the alloy group:
Aluminum, ->99.00%............................. lxx.x Aluminumalloys grouped by major alloying
element(s): Copper. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2xx.x Silicon,with added copper and/or
magnesium . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3xx.x Silicon . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4xx.x Magnesium . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5xx.x Zinc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7xx.x Tin . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8xx.x Other elements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9xx.x Unused series .................................... 6xx.x
For 2xx.x through 8xx.x alloys, the alloy group is determined by the alloying element present in the greatest mean percentage, except in cases in which the composition being registered qualifies as a modification of a previously registered alloy. If the greatest mean percentage is common to more than one alloying element, the alloy group is determined by the element that comes first in the sequence.
The second two digits identify the specific aluminum alloy or, for the aluminum (lxx.x) series, indicate purity. The last digit, which is separated from the others by a decimal point, indicates the product form, whether casting or ingot. A modification of an original alloy, or of the impurity limits for unalloyed aluminum, is indicated by a serial letter preceding the numerical designation. The serial letters are assigned in alphabetical sequence starting with A but omitting I, O, Q, and X, the X being reserved for experimental alloys. Explicit rules have been established for determining whether a proposed composition is a modification of an existing alloy or if it is a new alloy.
Aluminum Castings and Ingot. For the
lxx.x group, the second two of the four digits in the designation indicate the minimum aluminum percentage. These digits are the same as the two digits to the right of the decimal point in the minimum aluminum

percentage when expressed to the nearest 0.01%. The last digit indicates the product form: lxx.O indicates castings, and lxx.1 indicates ingot.
Aluminum Alloy Castingsand Ingot. For
the 2xx.x through 9xx.x alloy groups, the second two of the four digits in the designation have no special significance but serve only to identify the different alloys in the group. The last digit, which is to the right of the decimal point, indicates the product form: xxx.O indicates castings, and xxx.1 indicates ingot having limits for alloying elements the same as those for the alloy in the form of castings, except for those listed in Table 1.
Designations for Experimental Alloys
Experimental alloys also are designated in accordance with the systems for wrought and cast alloys, but they are indicated by the prefix X. The prefix is dropped when the alloy is no longer experimental. During development and before they are designated as experimental, new alloys may be identified by serial numbers assigned by their originators. Use of the serial number is discontinued when the ANSI H35.1 designation is assigned.
Cross-Referencing of Aluminum and Aluminum Alloy Products
Tables 2 and 3 cross-reference aluminum wrought and ingot/cast products according to composition, per Aluminum Association, Unified Numbering System (UNS), and International Organization for Standardization (ISO) standards.
Unified Numbering System. UNS numbers correlate many nationally used numbering systems currently administered by societies, trade associations, and individual users and producers of metals and alloys.
Aluminum Association International Alloy Designations. For wrought aluminum and aluminum alloys only, compositions may be registered with the Aluminum Association by a number of foreign organizations. These
organizations are signatories of a Declaration of Accord on the Recommendation for an International Designation System for Wrought Aluminum and Wrought Aluminum Alloys. In addition to the United States, the countries represented by signatories are Argentina, Australia, Austria, Belgium, Brazil, Denmark, Finland, France, Germany, Italy, Japan, Netherlands, Norway, Spain, Sweden, Switzerland, South Africa, and the United Kingdom. The European Aluminum Association is also a signatory.
Under ANSI standard H35.1, wrought aluminum or aluminum alloys will be registered in decreasing priority as national variations, as modifications, or as a new fourdigit number. A national variation that has composition limits very close but not identical to those registered by another country is identified by a serial letter following the numerical designation.
Castings and Foundry Alloys. There is no similar international accord for these aluminum or aluminum alloy products.
Foreign Alloy Designations. Historically, all major industrialized countries developed their own standard designations for aluminum and aluminum alloys. These are now being grouped under systems of the American National Standards Institute, the International Organization for Standardization, and the European Committee for Standardization.
The International Organization for Standardization has developed its own alphanumeric designation system for wrought aluminum and its alloys, based on the systems that have been used by certain European countries. The main addition element is distinguished by specifying the required content (middle of range) rounded off to the nearest 0.5:
5052=A1 Mg2.5
5251=A1 Mg2
If required, the secondary addition elements are distinguished by specifying the required content rounded off to the nearest 0.1, for two elements at most:
6181=A1 SilMg0.8
The chemical symbols for addition elements should be limited to four:
7050=A1 Zn6CuMgZr
If an alloy cannot otherwise be distinguished, a suffix in brackets is used:
6063=A1 Mg0.7Si
6463=A1 Mg0.7Si(B)
and international alloy registration
6063A=A1 Mg0.7Si(A)
Note that suffixes (A), (B), and so on, should not be confused with suffixes of the Aluminum Association.
The proposed ISO chemical composition standard for aluminum and its alloys references Aluminum Association equivalents as well as its own identification system. A listing of these is given in Table 4.
European Committee for Standardization. This committee (Comit6 Europren de Normalisation, CEN) of European Common Market members has developed a composition standard based on the ISO standard, but is proposing new designations not included in that standard. Some of these new designations are already registered as German (Deutsche Industrial-Normen, DIN) standards. The proposed standard also references Aluminum Association equivalents.
Temper Designation System for Aluminum and Aluminum Alloys
The temper designation system used in the United States for aluminum and aluminum alloys is used for all product forms (both wrought and cast), with the exception of ingot. The system is based on the sequences of mechanical or thermal treatments, or both, used to produce the various tempers. The temper designation follows the alloy designation and is separated from it by a hyphen. Basic temper designations consist of individual capital letters. Major subdivisions of basic tempers, where required, are indicated by one or more digits following the letter. These digits designate specific sequences of treatments that produce specific combinations of characteristics in the product. Variations in treatment conditions within major subdivisions are identified by additional digits. The conditions during heat treatment (such as time, temperature, and quenching rate) used to produce a given temper in one alloy may differ from those employed to produce the same temper in another alloy.
Basic Temper Designations
Designations for the common tempers, and descriptions of the sequences of operations used to produce these tempers, are given in the following paragraphs.

F, As-Fabricated. This is applied to prod-
ucts shaped by cold working, hot working, or casting processes in which no special control over thermal conditions or strain hardening is employed. For wrought products, there are no mechanical property limits.
O, Annealed. O applies to wrought products that are annealed to obtain loweststrength temper and to cast products that are annealed to improve ductility and dimensional stability. The O may be followed by a digit other than zero.
H, Strain-Hardened (Wrought Products
Only). This indicates products that have been strengthened by strain hardening, with or without supplementary thermal treatment to produce some reduction in strength. The H is always followed by two or more digits, as discussed in the section
"System for Strain-Hardened Products" in this article.
W, Solution Heat-Treated. This is an unstable temper applicable only to alloys whose strength naturally (spontaneously) changes at room temperature over a duration of months or even years after solution heat treatment. The designation is specific only when the period of natural aging is indicated (for example, W 1/2 h). See also the discussion of the Tx51, Tx52, and Tx54 tempers in the section "System for HeatTreatable Alloys" in this article.
T, Solution Heat-Treated. This applies to alloys whose strength is stable within a few weeks of solution heat treatment. The T is always followed by one or more digits, as discussed in the section "System for HeatTreatable Alloys" in this article.
System for Strain-Hardened Products
Temper designations for wrought products that are strengthened by strain hardening consist of an H followed by two or more digits. The first digit following the H indicates the specific sequence of basic operations.
H 1, Strain-Hardened Only. This applies to products that are strain hardened to obtain the desired strength without supplementary thermal treatment. The digit following the HI indicates the degree of strain hardening.
H2, Strain-Hardened and Partially Annealed. This pertains to products that are
strain-hardened more than the desired final amount and then reduced in strength to the desired level by partial annealing. The digit following the H2 indicates the degree of
