Aluminium die-cast alloy

The invention discloses an aluminium die-cast alloy which mainly contains Si, Cu, Fe, Mn, Mg, Zn, Ti and LaCe elements. The aluminium die-cast alloy is characterized in that weight content of all the elements are respectively as follows: 0.5% to 2.0% of Si, 0.1% to 0.5% of Cu, 0.3% to 0.8% of Fe, 0.5% to 1.0% of Mn, 2.0% to 4.0% of Mg, 0.8% to 2.0% of Zn, 0.15% to 0.2% of Ti and 0.6% to 0.8% of LaCe. The aluminium die-cast alloy has the good anodic oxidation ability, mechanical property and corrosion resisting property.
