Abstract: Provided is an aluminum alloy for die casting. The aluminum alloy includes: 3-10 wt % silicon (Si); 0.1-2.0 wt % magnesium (Mg); 0.01-1.3 wt % iron (Fe); 0.01-2.0 wt % zinc (Zn); 0.01-1.5 wt % copper (Cu); 0.01-0.5 wt % manganese (Mn); 0.01-0.5 wt % chrome (Cr); 0.01˜2.0 wt % lanthanum (La); 0.0˜12.0 wt % cerium (Ce); 0.0˜12.0 wt % strontium (Sr); rest aluminum (Al); and unavoidable impurities. The aluminum alloy is improved in not only corrosion-resistance but also physical properties.
