Description / Abstract:
Material Description. This material
specification applies to magnesium alloys for cast parts for
automotive and other allied industries. This standard governs only
the chemical composition of parts made with magnesium alloys that
represent common materials for identical product requirements
across GM worldwide. Casting processes, thermal treatments, casting
quality, microstructure, and mechanical properties are discussed,
but are not controlled by this standard. Many metallic elements
readily alloy with magnesium, but only a few are used in commercial
magnesium based alloys. Principle alloying elements include
aluminum (Al), zinc (Zn), manganese (Mn), silicon (Si), and rare
earth (RE) elements.
Symbols. Not applicable.
Applicability. Magnesium castings are widely
used in automotive applications. Typical applications and alloy
selection criteria for major subsystems are given in Appendix A,
Table A1.
