Abstract: Provided is a method for manufacturing an aluminum alloy exterior material for smart devices which is formed not by extrusion or die casting but by a strip casting method using a rotating mold, and an aluminum alloy exterior material manufactured by the method. In accordance with an embodiment, the method includes: preparing a molten aluminum alloy; casting the molten aluminum alloy into a sheet shape using a rotating mold to form an aluminum alloy cast sheet; and anodizing the aluminum alloy cast sheet, wherein in the forming of an aluminum alloy cast sheet, X in Equation 1 below may have a value in the range of greater than 0 and equal to or less than 0.15.
X=(WZn+WMg+WCu+WSi)/TC
Here, WZn+WMg+WCu+WSi is the total content (wt %) of zinc, magnesium, copper and silicon) in the aluminum alloy, and TC is the thermal conductivity (W/m·K) of the rotating mold.-
