EFFECT OF POURING TEMPERATURE ON IMPACT TOUGHNESS ON BRASS (Cu-Zn) THROUGH METAL CASTING

The purpose of this study is to investigate the impact toughness of brass (CuZn) with five variations of pouring temperature during the production of cast-samples through a metal casting process. Five variations of the pouring temperature are 1 060, 1 110, 1 160, 1 210, and 1 260 C-o, respectively. Meanwhile, the mold is produced from medium carbon steel and does not preheat (room temperature). The results show the maximum impact toughness is 20,67 Joule at 1 110 degrees C of pouring temperature, then the minimum impact toughness is 17,67 Joule at 1 260 degrees C of pouring temperature. In general, it can be concluded that the impact toughness decreases with increasing pouring temperature.
