Abstract

An ingot of recycled aluminum is usually used as a raw material to produce casting pans in small industries is used as a base material to produce samples of impact toughness and hardness in this study. The cast samples are produced by gravity casting using a metal mold. The pouring temperature is 760 °C (1400 °F), and the mold temperature is 220 °C (428 °F). The impact test specimens followed ASTM 23 standards for V-notch. The cooling curve during solidification is observed through a curve generated by data input. The impact toughness is tested by the Charpy method, and the hardness value is obtained by Brinell method. The impact toughness and hardness values of Al–Zn cast alloy are 7 J/cm2 and 38.43 BHN, respectively.
