The invention relates to the technical field of aluminum alloy machining, in particular to an aluminum alloy material for a mobile phone structural part and a preparation method of the aluminum alloymaterial. The aluminum alloy material is prepared from the components in percent by mass: 0.80-0.95% of Mg, 0.52-0.66% of Si, 0.52-0.66% of Cu, 0.12-0.28% of Mn, 0.05-0.18% of Zr, smaller than or equal to 0.1% of Fe, smaller than or equal to 0.10% of the sum of other impurities and the balance Al. The aluminum alloy material for the mobile phone structural part has high strength, toughness, surface treatment adaptability, tensile strength, yield strength, corrosion resistance and other performance, the strength is improved by one time or above, the tensile strength is larger than or equal to 380 MPa, the yield strength is larger than or equal to 340 MPa, the drop test does not affect the quality and performance of alloy, corrosion sensitivity or numbing or fogging is not generated during highlight mirror anode oxidized surface treatment, and the aluminum alloy material is high in corrosion resistance and suitable for mobile phone structural part materials treated with highlight mirrors.
