During the rolling process, the structure of the 3004/7072 composite is uniformly deformed, and the boundary line of the interface is straight and clear. The overlap rate of composite materials is relatively stable, and the deviation value of the overlap rate is 0. And 8%. Within. In the composite material, the grains of the core layer are fine, and the grains of the overlapping layer are larger than the grains of the core layer. Mn, Mg and Zn elements diffuse each other at the composite interface, and new grains are formed at the interface. 3004 with single layer. For aluminum alloy grades, the tensile strength and yield strength of composite materials are slightly reduced, while the elongation remains the same, and 7072 aluminum alloy as a laminated layer can protect the core material 3004 aluminum alloy. Therefore, 3004 7072 aluminum clad brazing coil strip for water tank of motorhome has both good mechanical properties and excellent corrosion resistance.
