The invention discloses a high-performance magnesium alloy plate. The high-performance magnesium alloy plate comprises, by weight, 0.1%-1.0% of Al, 0.1%-1.0% of Sn, 0.1%-1.0% of Ca and the balance Mgand inevitable impurities. According to the high-performance magnesium alloy plate, the process that a large number of rare earth elements such as Y, Ce and Gd are added in a traditional magnesium alloy plate preparation process is abandoned, the magnesium alloy plate is prepared by uniformly mixing Mg and common microelements Al, Sn and Ca, good comprehensive performance is achieved, and meanwhile the manufacturing cost of the magnesium alloy plate is reduced. 本发明公开了种高性能镁合金板材，各组分及其重量百分数为：Al为0.1-1.0％，Sn为0.1-1.0％，Ca为0.1-1.0％，余量为Mg和不可避免的杂质。本发明摒弃了传统镁合金板材制备工艺中加入大量的如Y、Ce、Gd等的稀土元素，而是通过Mg与普通微量元素Al、Sn和Ca均匀混合制备镁合金板材，具备良好的综合性能，同时降低了镁合金板材的制造成本。
