In this study, 1% and 4% pure magnesium were added to pure aluminum alloy by using pressure casting method.
These samples (7 mm x 20 mm) were homogenized at 520 ° C for 6 hours. Corrosion tests were performed by suspending
samples of certain sizes into 30 gr/l NaCl + 10 ml/l HCl solutions, measuring the mass loss. When we compare the produced
alloys, it is observed that as the magnesium addition increases, the weight loss increases and the corrosion resistance decreases.
In pure aluminum, 0.84 g/mm2 was achieved at the end of 24 hours, while the weight loss of the samples we added 4% Mg
increased by 300% to 2.23 g/ mm2. The decrease in the corrosion resistance is caused by the addition of Mg and the possible
formation of intermetallic (Al37Mg3 etc.) in the structure.
