Abstract

The invention belongs to the technical field of metal processing and particularly relates to an aluminum alloy shell for an electronic product. The aluminum alloy shell material is prepared from the following components by proportion: 4 to 8 percent of Mg, 0.5 to 0.9 part of Cu, 0.6 to 0.9 part of Fe, 0.3 to 0.7 part of Si, 0.4 to 0.6 part of Ca, 0.1 to 0.2 part of Zr, 0.2 to 0.3 part of Mn, 0.1 to 0.2 part of Cr, 0.05 or less than 0.05 percent of Ti, 0.02 or less than 0.02 percent of B, 0.01 or less than 0.01 percent of V and the balance of aluminum and unavoidable impurities. A preparation method of the shell comprises the following technical process: firstly, smelting and molding an aluminum alloy; secondly, carrying out hot processing on the aluminum alloy; thirdly, carrying out metalprocessing on the shell; fourthly, plating the shell. The aluminum alloy shell produced by the technology has the advantages of good thermal conductivity, good structural strength, good processing characteristics and excellent surface hardness and scratch resistance; in addition, due to the existence of a surface ceramic membrane, the shell has good anti-oxidation properties, good aesthetic feeling and good gripping hand feel.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to an aluminum alloy shell of an electronic product. Background technique [0002] With the improvement of the performance of mobile electronic products such as smartphones and the rapid development of the mobile Internet, terminal devices such as mobile phones and tablets have become an inseparable part of many people's lives. In addition to basic social communication, we can also use mobile phones and tablets to book airline tickets, shop, browse news, play games, etc. Because of this inseparable close connection, some people even compare these products to the "electronic organs" of the human body . [0003] Mobile phones and tablets are mainly composed of internal electronic components, LCD screens, batteries and shells, among which the shells play a role in supporting and protecting them. The current shells of electronic products are mainly composed of plas...
