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 (). The metallic cover is made of a metallic material that has a yield strength in the range from about 80 MPa to about 150 MPa, an elongation ratio in the range from about 15% to about 28%, and a hardness in the range from about 45 HV0.2 to about 70 HV0.2. A method for making the metallic cover is also provided.
