Stir-casting was done for manufacturing of Mg-6Zn alloy by adding Ca, Cu and Mn in micron sizes (44 microns). The phases formed and the surface morphology was analyzed with scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) followed by mechanical tests. The different phases found in the alloy enhances the strength of the material. When compared with other heat treated, RE included and mechanically worked alloys, Mg-6Zn exhibits better result. During the solidification process grain boundaries are formed due to higher denser intermetallic, thus the corrosion result proves as a better option for the alloys to be used in vehicles structural elements.
