N2 - The effect of addition of Sodium Chloride (NaCl) in increasing degasser efficiency on Al-Si12% casting has been carried out. Al-Si 12% casting product mechanical properties are a very important parameter that indicates the quality of the casting product. However, it is a very common phenomenon that the properties of the casting product was reduced by gas porosity defects, which is formed due to high solubility of H2 at melt temperature of Al-Si 12%. In this investigation, we used NaF and NaNO3 as degasser with the addition of NaCl in the casting process. The addition of NaCl was variated to see the capability of NaCl as a degasser. The casting process were conducted at melting temperature of 800 °C and pouring temperature of 690 °C. The mechanical properties between casting products that use NaF-NaNO3 degasser with variated ratio of NaCl addition were measured and compared. The result shows that mechanical properties of Al-Si12 cast product in this research will be decreased along with increasing number of NaCl addition ratio in degasser composition.
