Aluminum die casting alloy, aluminum die cast product and production process

摘要

An aluminum alloy for die casting, contains, in terms of mass percentage: Si in the range of 1.0~3.5%; Mg in the range of 2.5~4.5%; Mn in the range of 0.3~1.5%; Fe in the range equal to or less than 0.15%; Ti in the range of equal to or less than 0.20%; and the balance of aluminum and inevitable impurities. A die cast product having good strength and elongation in a high strain rate region is produced from the aluminum alloy without the need for solution heat treatment.
