In this work the mechanical and microstructure properties were studied on AZ92 alloy with the tin additions as an allowing element in as cast condition. In tin containing alloys, the tin were added in AZ92 alloys in two amounts, 3% and 6% respectively. The alloys were casted by the sand casting process in the foundry in the form of tensile test specimens. After sand casting the test samples were further analysed by chemical analysis, metallographic, XRD, Grain size measurement, Rockwell hardness and Yield strength Measurements. The effect of tin additions from the results analysis reveals the reduction in grain sizes as well as improvement in Rockwell hardness and yield strengths in tin containing AZ92 alloys as compared to AZ92 alloy.
