PURPOSE: A high-strength die casting aluminum alloy for thin products is provided to be used for exterior materials for a mobile communication terminal by ensuring high hardness, tensile strength, yield strength, and seizure resistance. CONSTITUTION: A high-strength die casting aluminum alloy for thin products comprises 4.0-5.0wt.% of Mg, 0.5-1.0wt.% of Si, 0.15-0.5wt.% of Fe, 0.3-0.4wt.% of Mn, 0.4wt.% max of Cu, 0.5wt.% max of Zn, and 0.05wt.% max of Ti. The strength of the alloy is enhanced by increasing the content of magnesium.
