Magnesium Extrusion Alloy Compositions

Provided Courtesy of Materials Technology@TMS | | | | | | | | | |
The following is a summary of the compositions of typical magnesium extrusion alloys.  Compositions are limits where a range is given for major alloying additions.  Compositions are nominal if a single value is given for intentional alloying additions.  Designations in parentheses are British designations for the ASTM designations which precede them. | | | For additional resources, visit http://www.materialstechnology.org | |
