PROBLEM TO BE SOLVED: To provide an aluminum wheel with the rigidity improved as compared to the conventional technique.SOLUTION: A load wheel made of aluminum alloy includes: a disk part which has a hub part and a design part radially formed from an outer circumferential surface of the hub part; and a rim part which includes a substantially annular rim main body part having the disk part internally arranged on one side end thereof, a first flange part disposed on one side end of the rim main body part and a second flange part disposed on the other end. Therein, 10.0 to 11.8 mass% of Si, 0.2 to 0.45 mass% of Mg, at least one kind of any of Fe, Cu, Mn, Zn and Ti and the balance Al and inevitable impurities are contained and the rigidity is 650 to 1750 (kN m/rad).SELECTED DRAWING: Figure 1
