Embodiment 1

[0029] refer to figure 1 , an aluminum alloy mobile phone casing, comprising a casing body 1, the surface of the casing body 1 is vacuum-coated with a nanoscale composite film layer 2. The thickness of the shell body 1 is 0.1-0.3mm. The thickness of the nanoscale composite film layer 2 is 200-300nm. The thickness of the shell body 1 is preferably 0.2 mm, and the thickness of the nanoscale composite film layer 2 is preferably 250 nm. The nanoscale composite film layer 2 is nano silver.

[0030] The shell body is an aluminum alloy profile.

[0031] The aluminum alloy profile is characterized in that: by weight percentage, it comprises the following components: 0.1-2wt% of Fe, 0.5-3wt% of Cu, 0.01-0.1wt% of B, 0.1-1wt% of Si, 0.5-3wt% of Zn, 0.1-2wt% of Ni, 0.1-2wt% of rare earth elements, 0.1-2wt% of Mo, and the rest are aluminum and unavoidable impurities.

[0032] The rare earth elements include at least one of La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, S...

Embodiment 2

[0038] An aluminum alloy profile, characterized in that: by weight percentage, it contains the following components: 0.1wt% of Fe, 1wt% of Cu, 0.01wt% of B, 1wt% of Si, 0.5wt% of Zn, 2wt% % Ni, 1wt% rare earth elements, 1wt% Mo, and the rest is aluminum.

[0039] Among the rare earth elements is La.

[0040] The first step is to smelt each raw material in proportion at 800°C, after stirring evenly, after refining, removing slag, and degassing, after standing at 770°C for 30 minutes, cast bars in the casting machine, and then lead the cast bars into the rolling mill , the temperature of the introduction into the rolling mill is 550°C, and the temperature of the exit is 420°C, which is heated during the hot rolling process.

[0041] In the second step, the aluminum alloy strips are cold-rolled into aluminum alloy strips of different sizes on a rolling mill.

[0042] In the third step, the aluminum alloy is subjected to solution heat treatment at 500° C. for 8 hours.

Embodiment 3

[0044] An aluminum alloy profile, characterized in that: by weight percentage, it contains the following components: 1wt% of Fe, 1wt% of Cu, 0.1wt% of B, 0.5wt% of Si, 2wt% of Zn, 0.7wt% % Ni, 0.9wt% rare earth elements, 1wt% Mo, and the rest is aluminum.

[0045] The rare earth element is Nd.

[0046] The first step is to smelt all raw materials in proportion at 780°C, stir them evenly, refine, remove slag, and degas, and keep them at 750°C for 30 minutes, then cast bars in the casting machine, and then lead the cast bars into the rolling mill , the temperature of the introduction into the rolling mill is 520°C, the temperature of the exit is 400°C, and it is heated during the hot rolling process.

[0047] In the second step, the aluminum alloy strips are cold-rolled into aluminum alloy strips of different sizes on a rolling mill.

[0048] In the third step, the aluminum alloy is subjected to solution heat treatment at 510° C. for 5 hours.

Abstract

The invention discloses an aluminum alloy mobile telephone shell comprising a shell body; the surface of the shell body is coated with a nanoscale composite film layer in a vacuum mode. The thicknessof the shell body is 0.1-0.3 mm. The thickness of the nanoscale composite film layer is 200-300 nm. The thickness of shell body is 0.2 mm, and the thickness of the nanoscale composite film layer is 250 nm. The nanoscale composite film layer is a nano-sliver layer. The shell body is aluminum alloy sections. The aluminum alloy sections using in the shell body has good high tensile strength, high yield strength, high extending rate, anti-corrosion property, and high-temperature stability, and the performance of the aluminum alloy sections is higher than iron pipe.

Description

technical field [0001] The invention relates to a mobile phone case, in particular to an aluminum alloy mobile phone case. Background technique [0002] According to statistics from the China Nonferrous Metals Industry Association, as of 2011, China's copper reserves were about 30 million tons, accounting for about 5% of the world's total reserves, and the supply of copper concentrates was less than 30%. The annual copper consumption was about 7 million tons, more than 70% depend on imports. [0003] Therefore, the development of suitable new materials to make the tensile strength and elongation close to the performance requirements of copper materials can not only greatly reduce investment costs, but also greatly save copper resources, while aluminum resources are abundant and have excellent mechanical properties and processing Performance, through appropriate modification, is a good substitute for copper materials, so the development of new aluminum alloy materials is the...
