Abstract
An exemplary metallic cover (20) includes a bottom base (21) and a plurality of side walls (22, 23, 24, 25). The side walls extend from bottom base. The bottom base and each of the side walls are connected by an edge structure (26). 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.
