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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
