Abstract Scope Lightweight magnesium (Mg) alloys have attracted considerable attention for potential applications in the automotive industries. However, the low strength or poor formability at room temperature (RT) hinders the wider applications of wrought Mg alloy sheets. We have developed new magnesium sheet alloys, i.e., Mg–1.2Al–0.5Ca–0.4Mn–0.8Zn and Mg–1.6Zn–0.5Ca–0.4Zr all in wt.%, that show large Index Erichsen values of about 8.0 mm in a solution treated (T4) condition due to a weak basal texture. Subsequent short time aging (T6) remarkably increases their 0.2% proof strengths to about 210 MPa. This improvement in strength by the T6 treatment is associated with a dense distribution of monoatomic layer Guinier–Preston zones on the basal planes of the Mg matrix. Our finding overcomes the trade-off relationship of the room temperature formability and proof strength in Mg alloy sheets and these can be used as “bake hardenable” magnesium sheet alloys with excellent RT formability.
