Abstract

This research used brass material or rubbing in remelting in induction kitchen, using CO2 sand mold with variation of cooling water of well water, SAE 40 oil and room temperature air. During the cooling process using different variations of cooling medium it can produce brass casting products with their own character and character. These properties are very influential on the quality of brass castings products. The purpose of this study was to compare the physical and mechanical properties of brass casting with different cooling media. Data analysis showed that from the test of chemical composition found some elements such as (Cu) 66,4%, (Zn) 27,9%, (Pb) 2,22%, (Sn) 1,38%, (Fe) 0,727 %, and (Ni) 0.401%. From HRB hardness test result obtained for variation of well water refrigeration media equal to 33,08 HRB, room temperature air cooling medium equal to 28,31 HRB, and SAE 40 oil refrigeration media equal to 27,98 HRB.
