Abstract

The invention relates to a preparing method of an aluminum alloy composite, in particular to a preparing method of the 1xxx / 5xxx aluminum alloy composite. According to the preparing method of the 1xxx / 5xxx aluminum alloy composite, an aluminum alloy composite finished product is finished through steps of core layer alloy and coating layer alloy board preparing, surface treatment, welding fixing, preheating, hot rolling, cold rolling and annealing; 1xxx series aluminum alloy and 5xxx series aluminum alloy are rolled to prepare the 1xxx / 5xxx aluminum alloy composite product in a composite manner, and advantage characteristics of the 1xxx series and 5xxx series aluminum alloy materials can be sufficiently combined; compared with an existing single 5xxx series aluminum alloy, the welding property of the prepared product can be obviously improved, meanwhile, good structural strength and corrosion resistance performance are achieved, punching molding is easy, and the requirement of a car wheel fender for punching molding and welding performance can be completely met.

Description

technical field [0001] The invention relates to a preparation method of an aluminum alloy composite material, in particular to a preparation method of a 1xxx / 5xxx aluminum alloy composite material. Background technique [0002] The fender is an important covering part in the car body. It is installed on the outside of the car wheel hub. During the driving process of the car, it mainly prevents the sand, gravel and mud rolled up by the wheel from splashing to the bottom of the car, and plays a role in protecting the chassis. Therefore, the materials used are required to have weathering resistance, good formability and certain strength. Traditional automobile fenders are mainly stamped from steel materials, and their processing and manufacturing processes are relatively mature and stable. [0003] With the tightening of emission regulations and the rapid development of new energy vehicles, vehicle lightweight is an important way and effective means to achieve energy saving an...
