Abstract

The invention discloses an aluminium alloy material, a mobile phone shell and a manufacturing method thereof. The aluminium alloy material comprises the following components in parts by weight: 1.2% to 2.3% of silicon, 2% to 4% of nickel, 1.4% to 2.6% of chromium, 1% to 3% of titanium and 0.02% to 0.08% of lanthanum rare earth, and the balance being aluminium. The aluminium alloy material comprises the components like nickel, chromium, titanium and lanthanum rare earth, and hardness, abrasion resistance and corrosion resistance of the aluminium alloy material can be improved through addition of the components; and besides, the aluminium alloy material is prepared through two-time inoculation, so that compactness of an aluminium ingot obtained through molten aluminium casting is good, poredefects are decreased, and performance of the aluminium alloy material is greatly improved. According to tests, tensile strength of the mobile phone shell manufactured through the aluminium alloy material provided by the invention is obviously improved, and abrasion resistance and pressure resistance of the entire mobile phone shell are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone case processing, in particular to an aluminum alloy material, a mobile phone case and a manufacturing method thereof. Background technique [0002] Due to its good feel and exquisite appearance, aluminum alloy mobile phone cases are very popular among consumers. [0003] At present, the manufacturing methods of the aluminum alloy mobile phone casing mainly include die-casting, extrusion plus CNC machining (CNC Machining, numerical control machining), stamping and the like. Among them, it is difficult to obtain a good anodizing effect for die-casting aluminum alloy, resulting in poor overall performance of the obtained mobile phone case. Although extrusion plus CNC process can obtain better anodic oxidation effect, the processing amount of CNC is large, the process is complicated, and the cost is high. In contrast, the stamping process not only has the advantage of low cost than the die-cast...
