Abstract
The purpose of this study is to study the effect of adding chemical elements contained in used lubricants which burn in cylindrical tube moulds on the hardness of aluminum alloys. Chemical elements in used lubricants have increased the hardness of aluminum alloys. The hardness of aluminum alloy which is not added with used lubricant, then the hardness is 57, 982 BHN, while by adding 6 ml used lubricant, the average hardness value is 61,439 BHN while adding 12 ml, the average hardness value decreases to 61, 271 BHN. This decrease is not too large, but it is noted that the value of hardness tends to decrease. When compared to the difference in the magnitude of the chemical composition between the sample pieces that are not so large, it can be said that the casting of bars is homogeneous.
