％とする。Lithium has a specific gravity of 0.53. By increasing the amount of lithium added, the lightweight and high strength magnesium alloy for casting of the present invention can have a further lower specific gravity. However, since lithium is active, an alloy added in excess of 16% by weight is susceptible to oxidation even if left alone in the atmosphere, and is not suitable as a practical alloy. When the amount of lithium added is less than 4% by weight, the specific gravity of the alloy is 1.
Since it is 65 or more, the merit of weight reduction is reduced. In the light weight and high strength magnesium alloy for casting of the present invention, the amount of lithium added is 4 to 16% by weight, preferably 8 to 14% by weight.

とする。In the lightweight high-strength magnesium alloy for casting of the present invention, calcium dissolves in the β phase (BCC phase) to harden the alloy, and suppresses aging such as recovery of the alloy. Contribute to In addition, calcium has the effect of crystallizing out as a fine Mg-Ca compound (intermetallic compound Mg 2 Ca) in the solidification stage and significantly refining the solidification structure, and can improve the strength. The solid solution hardening effect of calcium is clearly recognized when the amount of calcium added is 0.3% by weight or more.
However, if the added amount of calcium exceeds 5% by weight, Mg
Since the Ca-based compound crystallizes in the network at the grain boundaries, the alloy becomes brittle. Therefore, in the lightweight high-strength magnesium alloy for casting of the present invention, the amount of calcium added is 0.3 to 5% by weight, preferably 0.5 to 3% by weight.

Is known, and this effect is not offset by coexistence with calcium. The strength of the alloy increases with the addition of these alloying elements, but the alloy strength is 4% by weight for aluminum and zinc, and 2% by weight for silver, manganese, silicon, strontium, yttrium, scandium and lanthanoids. The effect of increasing the alloying strength is saturated, and no further increase in alloy strength is observed even if it is added more. On the other hand, 4 for aluminum and zinc
If the content of silver, manganese, silicon, strontium, yttrium, scandium and lanthanoid exceeds 2% by weight, the alloy may become brittle and the specific gravity of the alloy may increase. Therefore,
In the light weight and high strength magnesium alloy for casting of the present invention, the addition amount of aluminum and zinc is 4% by weight.
