Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a plated aluminum alloy casting having excellent strength, toughness, hardness, adhesiveness and brightness, and to provide a method for production of the aluminum alloy casting.SOLUTION: The aluminum alloy casting has an electroless nickel plating layer. The aluminum alloy contains, by weight, 1.5-5.5% Mg, 1.6-5.0% Zn, ≤0.4% Si, ≤0.4% Fe, ≤0.4% Cu, ≤0.2% Ti, ≤0.1% B, ≤0.1% Be, and the balance Al with inevitable impurities. The plated aluminum alloy casting is characterized by having a zincate treatment layer on the surface of the electrolytically polished casting and further having the electroless nickel plating layer thereon.
