WROUGHT ALUMINUM AND ALUMINUM ALLOYS

1.0 GENERAL

1.1 Purpose

This standard covers specific wrought aluminum and aluminum alloys, both heat treatable and non-heat treatable, and their commercially available tempers.

1.2 Purpose of the Material

The purpose of the material is for use in various applications.

1.3 Coverage of this Standard

This standard covers the material designation for engineering drawings correlating alloy, temper, product forms and requirements such as chemical composition, physical and mechanical properties. Specific requirements are derived from literature published by internationally recognized sources.

1.4 DaimlerChrysler Materials Designation

The Unified Numbering System (UNS) established jointly between the ASTM and SAE, reference ASTM DS 56 and SAE HSJ 1086, has identified the A9XXXX number series for the designation of wrought aluminum and aluminum alloys. To specify a wrought aluminum material, the DaimlerChrysler Material Standard Number MS-8580 will be followed by the appropriate UNS number code (A9XXXX) and, if it is an engineering requirement, there will be a temper designation as defined in Section 1.5. The basic form is MS-8580 - A9XXXX-XXX. Typical examples are shown in Table 1.

TABLE 1: EXAMPLES OF MATERIAL DESIGNATIONS

Non-Heat Treatable Alloys

Heat Treatable Alloys

i.e. MS-8580 - A95052 - H34 or

i.e. MS-8580 - A96061 - T6

i.e. MS-8580 - A95657 - H26

i.e. MS-8580 - A96063 - T42

1.5 Correlation to Other Standards

The UNS system provides a means of correlating a description of the alloy with the chemical composition and cross reference standards such as the American Society for Testing and Materials (ASTM), Society of Automotive Engineers (SAE), the Aluminum Association (AA), and the American National Standard (ANSI).

Tables 2 and 3 correlate the previously active Material Standard (MS) number and change letter with the above new Chrysler UNS designation as referenced in Section 1.4 above. Note, other materials not included in Tables 2 and 3 may be specified by using the format explained in paragraph 1.4 above.

1.5.1.1 Temper Subdivisions

Subdivisions of the basic tempers, where required, are indicated by one or more digits following the letter. Digits following H1, H2, and H3 indicate the degree of strain hardening. Tables 5 and 6 give examples of temper subdivisions for the H and T tempers respectively. A complete list of tempers as referenced in the American National Standard (ANSI) H35.1 is incorporated in the latest issue of either the AA Standards and Data Manual or SAE J993.
