CONTAINED IN VOL. 02.02, 2014 Specifies magnesium-alloy investment castings designated.

1.1This specification covers magnesium-alloy investment castings designated as shown in Table 1.

TABLE 1 Chemical Composition LimitsA
Note 1Analysis shall regularly be made for the elements specifically mentioned in this table. If, however, the presence of other elements is suspected or indicated in amounts greater than the specified limits, further analysis shall be made to determine that these elements are not present in excess of the specified limits.
Note 2The following applied to all specified limits in this table: For purposes of acceptance and rejection, an observed value or a calculated value obtained from analysis should be rounded off to the nearest unit in the last right-hand place of figures used in expressing the specified limit.

A Limits are in weight percent maximum unless shown as a range or stated otherwise.
B  These alloy designations were established in accordance with Practice B951.
C  Includes listed elements for which no specific limit is shown.
D If iron content exceeds 0.005 %, the iron to manganese ratio shall not exceed 0.032.
E Silver content for Alloy EQ21A shall be 1.3 to 1.7 %.
F Rare earth elements are in the form of didymium.
G Silver content for Alloy QE22A shall be 2.0 through 3.0 %.

1.2Alloy designations are in accordance with Practice E527; temper designations are in accordance with Practice B296.

1.3The values stated in inch-pound units are to be regarded as the standard. The SI values in parentheses are for information only.
