Abstract: Embodiments of the present invention provide a die casting aluminum alloy, including the following components in percentage by mass: 11.0% to 14.0% of silicon; 0.1% to 0.9% of manganese; 0.1% to 1.0% of magnesium; 0.3% to 1.4% of iron; less than or equal to 0.2% of copper; and aluminum and inevitable impurities. The die casting aluminum alloy has good formability, heat conductivity, and corrosion resistance, and certain mechanical properties, which can avoid problems of a low yield of die-casting fittings, burn-in caused by severe heat emission of a product, corrosion in a coastal environment, assembly difficulties caused by insufficient mechanical properties, severe deformation in a wind load condition, and the like, so as to satisfy requirements of global delivery of complex communications products.
