Abstract

The purposes of this study were: (1) Determine the effect of adding the element magnesium (Mg) in the aluminium foundry on Impact strength. (2) Determine the effect of the addition of the element magnesium (Mg) in the aluminium foundry on the level of hardness. (3) Determine the influence of the addition of the element magnesium (Mg) in the aluminium foundry to microstructure. This research uses descriptive quantitative method. This method is implemented by providing independent variables intentionally to the object of study to know the effect on the dependent variable research sample used is adding 2% and 5% of magnesium .Each specimen number 3 pieces of samples. Data obtained from the results of research put into the table, and displayed in graph form and then analyzed. Based on the results of this study concluded that: (1) the more elements of magnesium (Mg) are added, the value of impact strength aluminium casting result is increasing. (2), the more the element magnesium (Mg) are added to the value of the results of casting aluminium hardness is increasing. (3) the more the element magnesium (Mg) are added to the results of casting aluminium grain size get smaller.
