<p>Stir-casting was done for manufacturing of Mg-6Zn alloy by adding Ca, Cu and Mn in micron sizes (44 microns).&nbsp; 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.&nbsp; 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.&nbsp;&nbsp;<br></p>
