ASTM-B92 › Standard Specification for Unalloyed Magnesium Ingot and Stick For Remelting
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the standard for magnesium alloys in ingot and stick forms proposed for used in remelting. Magnesium 9980A alloys are available in ingot and stick form. Magnesium 9980B, 9990A, 9995A, and 9998A, on the other hand, are generally available in ingot form only. The specimens shall be produced with no slag and shall have a clean surface free from dirt, slag, or other foreign contaminants. Alloys shall adhere to specified chemical composition requirements. Any suitable chemical analysis method can be used unless otherwise prescribed.

1.1 This specification covers magnesium in the form of ingot and stick for remelting: 9980A is available in ingot and stick form, and 9980B, 9990A, 9995A, and 9998A are generally available only in ingot form.
1.2 The values stated in SI units are to be regarded as a separate standard. The values stated in each system are not exact equivalents, therefore each system must be used independently of the other.
1.3 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.
