scope:

This material specification covers the basic requirements for magnesium alloy ingots and is to be used for initial source validation of the ingot manufacturing process. It is implicit in this specification that the magnesium alloy ingots shall be of acceptable quality such that they can be cast into parts that will meet all relevant GM mechanical, chemical, and performance requirements.

Reference GM9839P for the process and requirements a magnesium producer must satisfy to qualify their ingot production process.

Material Description. The systems of magnesium alloys commonly used for automotive high pressure die casting are: magnesium-aluminum-zinc (AZ), magnesium-aluminum-manganese (AM), and magnesium-aluminum-silicon (AS).
