Abstract: Embodiments of the present disclosure provide a die casting aluminum alloy, including constituents with the following mass percentages: silicon: 4.0% to 10.0%; magnesium: 0.2% to 1.0%; copper: ≤0.1%; manganese: ≤0.1%; zinc: ≤0.1%; ferrum: ≤1.3%; titanium: ≤0.2%; inevitable impurities: ≤0.15%; and the rest: aluminum. The die casting aluminum alloy has a high heat-conducting property, good formability, high corrosion resistance, and a good mechanical property. This can resolve a prior-art problem that forming and heat dissipation requirements of a communications product with a complex structure, high heat flux density, and large power cannot be met at the same time because it is difficult for a die casting aluminum alloy to have both a high heat-conducting property and good formability. The embodiments of the present disclosure further provide a production method of the die casting aluminum alloy and a communications product.
