The results show that the specific conductivities of alloys modified by Sb and Sr have high values, while the specific conductivity of alloy modified by RE displays low values and that the farther the distances from the bottom of the ingots, the smaller the specific conductivities of the Sb or Sr modified alloys are. It is indicated that solid solution treatment at 535℃ increases the specific conductivity of the unmodified alloy, but decreases the values of the Sb or Sr modified alloy and the higher the specific conductivity, the higher the impact toughness of the ingots is.
