A method for making a metallic cover including the following steps. Drawing an aluminum alloy sheet that has a yield strength in a range from about 80 MPa to about 150 MPa, an elongation ratio in a range from about 15% to about 28%, and a hardness in a range from about 45 HV0.2 to about 70 HV0.2 to form a preformed cover. The preformed cover includes a bottom base and a plurality of side walls, and each of the side wall and the bottom base are connected by a curved-cornered edge. Pressing the curved-cornered edge of the preformed cover into a sharp-cornered edge structure by a forming die. Polishing the preformed cover. Anodizing the polished preformed cover to form the metallic cover.

Method for making metallic cover

An exemplary metallic cover () includes a bottom base () and a plurality of side walls (). The side walls extend from bottom base. The bottom base and each of the side walls are connected by an edge structure ().
