Problems solved by technology

6063 aluminum alloy has better anodic oxidation performance, but its strength is lower; the strength of 6061 aluminum alloy is higher than that of 6063 aluminum alloy, but the anodic oxidation effect of the material is slightly worse than that of 6063 aluminum alloy
The strength and anodic oxidation performance of aluminum alloy materials are affected by the alloy composition, that is, high strength needs to be achieved through high alloying, but high alloying will deteriorate the anodic oxidation effect
At the same time, the published patent application document (Patent Publication No. CN 108396209A) discloses an aluminum alloy composite material, which is made of 6 series and 7 series aluminum alloys, although the strength and The anodic oxidation effect has been improved, but due to the large difference in the heat treatment process between the 6-series aluminum alloy and the 7-series aluminum alloy, it is necessary to take into account the heat treatment processes of the two different metals at the same time, so the material still has disadvantages such as low surface hardness and easy scratches.
At present, with the continuous development of electronic products, the performance of the 6 series aluminum alloy materials prepared by the existing technology is becoming more and more difficult to meet the requirements of high strength and anodic oxidation performance

Abstract

The invention relates to a preparation method of an aluminum alloy composite material, in particular to a preparation method of the aluminum alloy composite material for an outer part of an electronicproduct. The preparation method of the aluminum alloy composite material comprises the following steps: carrying out preparation of core layer alloys and cladding layer alloy plates, carrying out surface treatment, carrying out welding and fixing, carrying out pre-heating, carrying out hot rolling, carrying out cold rolling, carrying out solid-solution hardening, and carrying out aging to obtainan aluminum alloy composite material finished product. According to the preparation method of the aluminum alloy composite material disclosed by the invention, rolling compounding on a 6-series aluminum alloy with low alloying and high anode oxidation performance and a 6-series aluminum alloy with higher strength is carried out, so that an aluminum alloy composite material product for the outer part of the electronic product is prepared. Compared with a single 6-series aluminum alloy material in the prior art, the product prepared by adopting the method disclosed by the invention has the bothcharacteristics of high strength and excellent anode oxidation effect, and therefore, the product is a desired material which is used for manufacturing the outer part of the electronic product.

Description

Technical field [0001] The invention relates to a method for preparing an aluminum alloy composite material, in particular to a method for preparing an aluminum alloy composite material for appearance parts of electronic products. Background technique [0002] Aluminum alloy materials have the advantages of light weight, high strength, good heat dissipation, and surface oxidation treatment with bright and beautiful colors, and are gradually replacing steel and plastics as the preferred material for the appearance of 3C electronic products such as mobile phones, tablet computers, and notebook computers. There are three main series of aluminum alloys for appearance parts of 3C electronic products: 5 series, 6 series and 7 series. Among them, the 5 series aluminum alloy has good anodizing effect, but the hardness is low, and the protection effect of the product is limited; the 7 series aluminum alloy has the highest strength and hardness, which can provide sufficient guarantee for t...
