It is preferred that, the technique of step (1) aluminium alloy smelting, be the XR348 aluminium alloys that will be prepared component it is load melting, Take off after slag, when melt temperature reaches 740~760 DEG C, zr element has directly been thrown into aluminium in the form of aluminium zirconium hardener and melted In pond, it is stirred, melts the melting for completing aluminium alloy for 15~30 minutes;The mass fraction of zirconium is 0.1- in aluminium zirconium hardener 15%.
The advantages of the present invention are:
The short quality of preparation method flow of the present invention is high, and aluminium foil has high deposited strength after high temperature brazing and corrosion resistance is excellent It is good, it is ensured that pipe-fin structure has excellent sink-resistance performance in soldering, the shape that will not collapse and corrode;
The present invention uses Al-Mn-Si-Fe-Zn-Zr alloy system XR348 alloys, and its manganese, iron, silicon alloy composition proportioning are 1.2:1:1, branching shape or bulk (FeMn) can be produced3SiAl12Two-phase compound, the second of these indissolubles can break in deformation It is broken and be elongated, there is banded structure, particle is linearly arranged along deformation direction, be made up of short mutual disjunct strip, In high temperature brazing, the second phase compound small and dispersed of these indissolubles is distributed in around thick recrystallization crystal boundary, can prevent pricker Layer silicon atom spreads, so as to improve the sink-resistance performance of material.Micro zirconium, can produce micro ZrAl3Two-phase compound, The recrystallization temperature of alloy is greatly improved, recrystallization process is hindered, the solderability and anti-stress corrosiveness of alloy can be improved Energy.
Moved back before the sink-resistance performance and blank species of aluminium foil and its cold working rate and finished product of final pass in the middle of a time Fiery temperature is relevant.It is more serious that hot rolling ingot homogenizing annealing tissue is compared in the segregation of continuous casting and rolling organization center with component segregation, There is data to suggest that, the initial tensile strength 10~20MPa bigger than hot rolling blank of the continuous casting and rolling blank of same thickness;Cold working rate One timing, annealing temperature is higher, and aluminium foil is sagging more serious;The timing of annealing temperature one, cold working rate is critical less than recrystallization annealing Degree of deformation, after recrystallization annealing, aluminium foil recrystal grain meeting abnormal growth, intensity can drastically decline, and aluminium foil is sagging serious;Annealing The timing of temperature one, cold working rate is bigger, and distortion of lattice can be bigger, and aluminium foil recrystallization temperature is lower, aluminium foil after recrystallization annealing Intensity it is lower, aluminium foil is more easy to be sagging.Therefore, selection continuous casting and rolling blank is under certain annealing temperature, reasonable selection The size of cold working rate, control aluminium foil grain size is uniformly distributed in the range of 3~4 grades, contributes to aluminium foil at 600 ± 20 DEG C The raising of sink-resistance performance under high-temperature baking.
The present invention uses XR348 alloys to produce car radiation fin aluminium foil for raw material, and weld seam has excellent after high temperature brazing Corrosion resistance, it is ensured that after brazing, through Kesternich test, weld seam preferentially radiating fin will not corrode pipe-fin structure.
Because solubility of the zinc in aluminium is big, 0.8~1.0% a small amount of zinc is added in alloy, to the mechanical property of alloy Have no significant effect.On the premise of high temperature brazing Weld strength is not lost, a small amount of zinc can reduce the electrode potential of fin aluminium, Fine aluminium is -0.8~-0.85 volt, and the electrode potential of alloy containing zinc 2% is -1 volt, contributes to aluminum alloy fin prior to weldering Seam and pipe corrosion, suppress fluid hose and occur corrosion failure.
