Embodiment Construction

[0019] Aluminum alloy composite materials for heat transmission are welded aluminum alloy strips of different materials, rolled together at high temperature and high pressure on a hot rolling mill, and then cold rolled to finished products. According to different performances, each layer has the function of each layer. The composite material consists of two to three layers: ① its first layer is used for brazing, the second layer is the substrate, and the third layer is the waterproof layer; ② both sides of the substrate are composite brazing layers; ③ one side of the substrate is composite brazing layer.

[0020] Composite material matrix adopts AA3003, brazing layer adopts AA4343 or AA4045, and waterproof layer adopts AA7072. The selection of materials combines the advantages of core material and cladding layer material.

[0021] This embodiment describes the present invention in detail with a three-layer composite material.

[0022] The first step: according to the performa...

Abstract

The invention discloses a preparation method of aluminum alloy composites for brazing heat transmission. It treats the pre-welding matrix and coating surface by using techniques including polishing, high pressure wind and alcohol cleaning, which can get flat surfaces without mark or filth and material structures without bleb or impurity. Milling is finished based on homogenizing treatment to avoid oxidation of the processing surface. The invention is reliable and practical and has on pollution on environment. According to the tests of the special inspection department, the products' performances can meet the standard requirements, which get good evaluations from users.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a method for manufacturing an aluminum alloy composite material for brazing heat transmission. Background technique [0002] With the development of modern industry, people's requirements for materials are getting higher and higher. A single material of aluminum alloy sheet, strip and foil can no longer meet people's higher requirements. Composite materials can meet people's higher requirements, and the main trends in the development of aluminum alloy composite materials for heat transmission are: [0003] ① Composite materials have good thermal and mechanical properties. Composite materials for heat exchangers with high strength, corrosion resistance, and good thermal stability can reduce the thickness of heat exchanger materials or work under higher pressures, and can make heat exchangers more compact, further reducing weight and reducing cost. [0004] ② T...
