Abstract

The invention discloses an aluminum alloy sheet for a lateral plate of an automobile radiator and a manufacturing method for the aluminum alloy sheet. The aluminum alloy sheet for the lateral plate of the automobile radiator is characterized by comprising a natural aging layer, heat transfer layers, a brazing layer and an anticorrosive coating, wherein the brazing layer and the anticorrosive coating are respectively arranged on two sides of the natural aging layer; one heat transfer layer is arranged between the brazing layer and the natural aging layer; and the other heat transfer layer is arranged between the anticorrosive coating and the natural aging layer. The manufacturing method for the lateral plate of the automobile radiator comprises the steps of a smelting step, a saw cutting step, a face milling step, a hot rolling step, a welding step, a heating step, a hot rolling step, a cold rolling step, an annealing step of a finished product and a crosscut shearing step. The manufacturing method is characterized in that the smelting step comprises steps of smelting the natural aging layer, smelting the heat transfer layers, smelting the brazing layer and smelting the anticorrosive coating. The aluminum alloy sheet and the manufacturing method disclosed by the invention have the advantages that the strength of materials is gradually enhanced in air after the materials are processed, so that the strength of the lateral plate of the finished product of the radiator is improved, the thickness of the lateral plate is reduced, and the aims of reducing production cost of the automobile, saving energy and reducing emission are achieved.

Description

technical field [0001] The invention relates to an aluminum alloy composite material, in particular to an aluminum alloy plate for an automobile radiator side plate. [0002] The invention also relates to a method for manufacturing the aluminum alloy plate used for the side plate of the automobile radiator. Background technique [0003] At present, the side plate materials of automobile radiators require higher strength, the better, but the follow-up processing of high-strength aluminum alloy plates is complicated, and defects such as cracking are prone to occur. Therefore, we can only choose the soft state to increase the thickness of the plate to ensure the firmness of the radiator side plate. With the continuous decline of automobile prices and the lightweight demand for energy saving and emission reduction, automobile radiator manufacturers urgently need an ultra-thin side panel that is easy to process and has high finished product strength. [0004] Therefore, there i...
