MgAlZn
MgAlZn refers to a family of magnesium alloys in which aluminum and zinc are the primary alloying elements. This class is most commonly represented by the AZ-series, which are valued for a favorable combination of light weight, strength, and castability. The composition typically includes aluminum in roughly the 3–9 wt% range and zinc in about 0.5–1.5 wt%, with magnesium making up the balance. Variants such as AZ31, AZ63, and AZ91 differ mainly in aluminum content, affecting strength and creep resistance.
The microstructure of MgAlZn alloys features secondary phases such as Mg17Al12, which can contribute to precipitation
Manufacturing methods for MgAlZn alloys include die casting and other casting processes, as well as wrought
Applications for MgAlZn alloys span automotive components (engine and transmission housings, valve covers), electronics enclosures, sports
