ASTM B92/B92M-01

Standard Specification for Unalloyed Magnesium Ingot and Stick For Remelting

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.
