Magnesium Forging Alloy Compositions

Provided Courtesy of Materials Technology@TMS | | | | | | | | | | | | | | | | | |

The following is a summary of the compositions of typical magnesium forging 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.
