A reinforced aluminum alloy with high electric and thermal conductivity of the present invention has the weight percentage below : Mg 0.61˜0.65%, Si 0.4˜0.45%, rare earth elements 0.21˜0.3%, B 0.03˜0.10% and the balances essentially Al and unavoidable impurities. The reinforced aluminum alloy enhanced the containing of Mg and Si elements compared to the conventional aluminum alloy such as 6063, and controlled the containing of the Mg and Si in a certain relatively narrower range so as to control the desired quality of the aluminum alloy. At the same time, a Ce of the rare earth elements and B element are added into the aluminum alloy and completely solid melted the added alloys to the aluminum alloy. It is not only remaining the strength of the aluminum alloy, but also increasing the electric and thermal conductivity.
