A flame-resistant magnesium alloy and a preparation method therefor, relating to the fields of magnesium based alloys and alloying. According to the magnesium alloy, a certain quantity of calcium and yttrium are added by using a smelting metallurgy method on the basis of die casting of the magnesium alloy. The preparation method for the magnesium alloy comprises: preparation of materials, preheating, feeding, smelting, refining and slag removal, slagging and die casting. While excellent die casting manufacturability and low cost of a die cast magnesium alloy are maintained, an ignition point of the die cast magnesium alloy can be remarkably increased, and high-temperature oxidation resistance of the magnesium alloy is improved, so that the flame resistance is improved, and an application range of the magnesium alloy is further expanded. La présente invention concerne un alliage de magnésium ininflammable et son procédé de préparation se rapportant aux domaines des alliages à base de magnésium et aux processus
