Abstract
A magnesium alloy can include magnesium, about 3.4 wt % to about 5.5 wt % aluminum, about 0.40 wt % to about 1.5 wt % zinc, and about 0.26 wt % to about 0.36 wt % manganese. The magnesium alloy may exhibit an ultimate tensile strength from about 210 MPa to about 260 MPa, a yield strength from about 100 MPa to about 135 MPa, and an elongation from about 8% to about 15%. The magnesium alloy may exhibit a bend angle from about 46° to about 54°.
