Full Description

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

Reference GM9839P for the process and requirements a magnesiumproducer must satisfy to qualifytheir ingot production process.

Material Description. The systems of magnesium alloys commonly usedfor automotive high pressuredie casting are: magnesium-aluminum-zinc (AZ),magnesium-aluminum-manganese (AM), andmagnesium-aluminum-silicon (AS).
