1. A magnesium alloy, consisting of:
0.5-1.6 wt % of Zn;
0.3-0.5 wt % of Ca;
at least 0.2 wt % of Zr; and
the remainder consisting of Mg and unavoidable impurities
wherein
a Guinier-Preston Zone precipitate comprising Mg, Ca and Zn is dispersed on the (0001) plane of a magnesium matrix and has a plate-like shape, and
an Index Erichsen value at room temperature is 7.0 mm or higher.
