Preparing process of aluminum alloy for mobile phone shell

Abstract

The invention discloses a preparing process of an aluminum alloy for a mobile phone shell. The aluminum alloy comprises, by weight percent, 3 to 6% of Zn, 1 to 2% of Mg, 0.5 to 2% of Cu, 0.5 to 1.5% of Si, 0.01 to 0.1% of B, 0.5 to 1% of Fe, 0.1 to 2% of Ni, 0.1 to 2% of Mo, not larger than 0.02% of Cr, not larger than 0.025% of Ti, not larger than 0.1% of Zr, 0.2 to 1% of rare earth, not larger than 0.01% of other single impurities and the balance aluminum. The aluminum alloy prepared through the process improves the preparing process of an existing aluminum alloy, on the basis of ensuring strength and machining performance of the aluminum alloy, the friction resistance properties and excellent heat conduction properties are considered, and the aluminum alloy is suitable for being used inthe mobile phone shell.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy preparation technology, in particular to an aluminum alloy preparation process for a mobile phone casing. Background technique [0002] Aluminum alloy has excellent mechanical properties and processing properties, and is now widely used in structural parts of electronic products. Aluminum alloys for mobile phone casings are required to have a certain strength, hardness, grain size, and surface coarse-grained layer thickness. In the prior art, aluminum alloys that can be applied to mobile phone casings are easily deformed due to strength problems, and after processing, due to the grain structure The reason is that the surface effect is not good. In addition, the problem of heat dissipation needs to be solved. The aluminum alloys used for mobile phone casings in the prior art usually have low thermal conductivity, which cannot meet the heat dissipation requirements of mobile phones, resultin...

Aluminum alloys for mobile phone casings are required to have a certain strength, hardness, grain size, and surface coarse-grained layer thickness. In the prior art, aluminum alloys that can be applied to mobile phone casings are easily deformed due to strength problems, and after processing, due to the grain structure The reason, the surface effect is not good

In addition, the problem of heat dissipation needs to be solved. The aluminum alloys used for mobile phone casings in the prior art usually have low thermal conductivity, which cannot meet the heat dissipation requirements of mobile phones, resulting in safety problems and affecting the service life of mobile phones.
