Abstract
Magnesium alloys containing, by mass percent, Al: 10.0 to 13.0%, Si: 0.3 to 1.5%, Mn: 0.1 to 1.0%, and, if desired, Zn: less than 0.8%, the rest being Mg and unavoidable impurities. Neither cracking by the casting is invited nor the mechanical property is spoiled, and the fluidity can be notably improved, and it is possible to make products small in thickness and light in weight.
