Abstract
A heat-resistant magnesium alloy is for casting, and includes Ca in an amount of from 1 to 15% by mass, Al in a summed amount of from 4 to 25% by mass with the amount of Ca, and the balance being Mg and inevitable impurities when the entirety is taken as 100% by mass. The heat-resistant magnesium alloy is not only inexpensive, but also effects an advantage that cracks are inhibited from occurring when being cast. For example, a process for producing heat-resistant magnesium alloy cast product includes the step of pressure pouring an alloy molten metal, which has a target composition around Mg—3% Ca—3% Al—from 0.2 to 0.3% Mn, into a cavity of metallic die, which is preheated to a die temperature of from 130 to 140° C. in advance. The process makes it possible to produce die-cast products, which are free from cast cracks.
