This paper presents the results of an experimental investigation of the mechanical properties of spheroidal graphite (SG)
iron where varying percentage of magnesium using as an inoculants. Total four test samples were carried out. The specimens
were subjected to tensile strength, yield strength, percentage of elongation, hardness and percentage of modularity. The results
indicate that the prediction percentages of Mg are not accurate. By help of formula, prepared four samples of different percentage
of Mg (0.025%, 0.030%, 0.035%, and 0.040). Based on the experimental results this paper evaluate that S.G iron having the Mg
about 0.035% in its final composition will give good mechanical properties as well as the desirable microstructure having the
higher number of nodules.
