Abstract
This specification covers magnesium-alloy extruded bars, rods, profiles, tubes, and wire. The bars, rods, profiles, tubes, or wire shall conform to the chemical requirements specified.
Tensile properties such as tensile strength, yield strength, and elongation of magnesium alloys shall be determined. All material shall be of uniform quality, free from injurious surface
defects, and shall have a workmanlike finish.
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-alloy extruded bars, rods, profiles, tubes, and wire of the composition given in Table 1 .
TABLE 1 Chemical Requirements A
Note 1 Analysis shall regularly be made only for the elements specifically mentioned in this table. If,
however, the presence of other elements is suspected or indicated in the course of routine analysis to be in amounts greater than the specified limits, further analysis shall be made to
determine that the total of these other elements is not in excess of the limits specified in the last column of the table.
Note 2 The following applies 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.

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.
