The purpose of this study to evaluate the effect of pouring temperature on the Vickers hardness of CuZn brass alloys through metal casting. The pouring temperature varied from 1,060; 1,110; 1,160; 1,210; and 1,260 °C; while metal molds were not given preheat treatment or at room temperature conditions. The results obtained that the maximum hardness is 616 HV shown at 1,210 °C of the pouring temperature, while the minimum hardness is 574 HV can be seen at 1,210 °C of the pouring temperature. The significance of the difference in casting temperature on the hardness of CuZn brass alloy through metal casting was analyzed using one-way ANOVA. Generally, it appears that hardness increases with increasing pouring temperature. The effect of pouring temperature results in differences in solidifying rates and freezing intervals of brass alloys. Furthermore, it affects the grain structure growth of the brass alloy which led to the difference in Vickers hardness.
