Abstract (en)

[origin: EP3954798A1] Disclosed are a die-cast aluminum alloy, a method for preparing the die-cast aluminum alloy, and a structural member for a communications product prepared by using the die-cast aluminum alloy. The die-cast aluminum alloy includes the following components in mass percentages: 0.1-7% of magnesium, 7-35% of zinc, 0.2-0.8% of manganese, 0.1-0.7% of iron, 0.07-0.2% of titanium and/or zirconium, with the inevitable impurities being ≤0.3%, and the balance being aluminum. The die-cast aluminum alloy features high strength, high toughness, and excellent fluidity, and is applicable to molding complex thin-walled products.
