Abstract

The invention discloses a brazing aluminum alloy composite. The brazing aluminum alloy composite is prepared from an alloy AA4045, an alloy AA3003 and an alloy Mod6060. A method includes the followingsteps that the three alloys are produced, the alloy AA4045 is arranged on the outer layer, the alloys AA3003 are arranged in the two middle layers, the surface of the alloy Mod6060 is arranged on theinner layer, the alloys are cleaned and then welded together through argon arc welding, hot rolling and cold rolling are performed, the composite is machined to have the predetermined thickness ranging from 1.5 mm to 2.5 mm according to the cold working rate being 20%-30%, recrystallization annealing is performed at the thickness at the annealing temperature ranging from 405 DEG C to 415 DEG C, the temperature is kept for 2-3 h, and a finished product is obtained through flattening and shearing after being discharged out of a furnace. The alloy layers have the effects as follows: the alloy AA4045 mainly has the welding effect, the alloy AA3003 has the isolation effect, and the alloy Mod6060 has the effects of strength enhancing through ageing strengthening and collapse resisting.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a brazing aluminum alloy composite material. Background technique [0002] At present, the brazed aluminum alloy used for the main board of automobile radiator heat exchanger in my country is mostly a two-layer or three-layer composite board material, which is not strong enough, will collapse after a period of use, has poor fatigue resistance, and is not strong in heat exchange. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the defects of the prior art such as complicated steps and high production cost, and provide a preparation method of brazing aluminum alloy composite material. The preparation method of the brazing aluminum alloy composite material has the characteristics of reducing energy consumption, reducing product cost, and the like. [0004] In order to achieve the above object, the present inventi...
