Magnesium Sand and Permanent Mold
Casting Alloy Compositions

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

The following is a summary of the compositions of typical magnesium sand & permanent mold casting 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.
