1.1 This specification covers magnesium alloys in sheet and plate form designated as shown in Table 1.

1.2 The values stated in either inch-pound or SI units are to be regarded separately as standards. The SI units are shown in brackets or in separate tables or columns. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.

1.3 Unless the order specifies the “M” specification designation, the material shall be furnished to the inch-pound units.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


This specification covers magnesium-alloy sheet and plate designated as AZ31B in temper types O, H24, and H26. The sheet and plate shall conform to the chemical composition requirements prescribed for magnesium, aluminum, manganese, zinc, calcium, copper, iron, nickel and silicon, and shall meet the specified requirements for the tensile properties such as tensile strength, yield strength, and elongation for the corresponding specified thickness. Requirements for chemical analysis and tensile test including sampling are detailed.
