An aluminum alloy, according to the present invention, comprises: 1-2 wt% of Main body, 1-2 wt% of Cu, 1-2 wt% of Zn, 0.5-2 wt% of Ni, and the remainder consisting of Al and inevitable impurities. The heat conductivity at an ordinary temperature of 25°C is less than 185 W/m*k, and the heat conductivity at a high temperature of 200°C is greater than or equal to 185 W/m*k. The heat conductivity at a high temperature of 200°C is higher than the heat conductivity at an ordinary temperature of 25°C. |
