At present, the metal materials for manufacturing the electronic product shell are mainly aluminum alloys, and magnesium aluminum alloys and titanium alloys are also common metal materials for manufacturing the electronic product shell.
The conventional technology generally extrudes aluminum alloy to a base material or performs die-casting molding, then the aluminum alloy is manufactured into a shell of an electronic product through a mechanical cutting process, and then the shell is subjected to anodic oxidation treatment to obtain the final required shell. Thin metal plate or strip products cannot be produced by extrusion, the extruded products can only meet the requirement of thinning and shelling through a large amount of machining, and the production process is complex. The die-casting product has large machining amount, die-casting waste is easy to oxidize and has high impurity content, and a plurality of defects are easy to generate in the forming process, so that the production cost of the product is increased.
In order to solve the problem of manufacturing the shell by adopting an extrusion or die-casting process, the shell of the electronic product can be quickly formed by adopting a thin metal plate or metal strip through a stamping process, and the shell of the electronic product can be light and thin through simple machining, grinding, sand blasting and polishing treatment. At present, a commonly used 6-8 series aluminum alloy sheet or strip can be changed into a hard roll/plate material after being treated by high-temperature T4, and is not easy to be formed by a stamping process.

As the preferable structure of the metal composite plate of the invention, the treatment temperature of the aluminum alloy plate of 6-8 series passing through the high temperature T4 treatment process is 440-660 ℃, and the treatment temperature of the aluminum alloy plate of 1-5 series passing through the high temperature T4 treatment process is 450-650 ℃.
The metal composite plate has the beneficial effects that the first metal plate is formed by adopting 6-8 series aluminum alloy plate soft materials and then is treated by high-temperature T4, so that the metal composite plate is easy to process and deform and has enough mechanical strength; the second metal plate and the third metal plate are made of 1-5 series aluminum alloy and are subjected to T4 treatment simultaneously to form soft materials which are easy to punch and form or bend. On the other hand, 1-5 series aluminum alloy is adopted as the outer layer structure of the metal composite plate, so that the anode treatment and the subsequent coloring treatment can be carried out, and the problem of attractiveness can be solved. 6-8 series aluminum alloy plates or magnesium alloy plates are used as the middle layer of the metal composite plate, so that the problem that the anode aluminum plate is insufficient in compression resistance, tensile strength and yield strength can be solved.
