A die-cast aluminium alloy comprises the following components in percentage by weight: 1.0-4.0 wt% of Mn, 0.50-2.50 wt% of Zn, 0.1-0.5 wt% of Zr, 0.1-0.5 wt% of Fe, and the balance being Al and impurities. The total content of impurities is less than or equal to 0.2 wt%, wherein impurity Si is less than or equal to 0.1 wt%, and impurity Cu is less than or equal to 0.1 wt%. The preparation method for the die-cast aluminium alloy comprises the steps of material preparation, drying, smelting, refining, die-casting and anodizing. |
