“…The bonding of different aluminum alloys for braze-used products can be performed via the already mentioned hot rolling [12], where the bond criterion and its correlated parameters can be predicted. Movahedi et al [13] studied the roll bonding behavior of EN AW 3003 with EN AW 4043 and EN AW 3003 with a Zn sheet and concluded that the first-mentioned clad combination was bonded with higher joint strengths and lower threshold reductions in thickness compared to the second mentioned analyzed cladded combination. The evolution of the grain structure in both-sided clad EN AW 3003 with EN AW 4343 was investigated by Kim et al [14], but the comparison of corrosion resistance for cold-rolled and post-brazed material was not reported, and that is the novelty in this article.…”

The present study investigates the accumulative roll bonding process applied to the EN AW 3003 aluminum alloy, serving as a composite material on both sides and consisting of the EN AW 4343 aluminum alloy. For the characterization of the optical microscopy, corrosion tests with saltwater acetic acid and mechanical properties before and after the braze test were employed. The numerical simulations accurately predicted the industrial cold rolling values for the rolling force and surface temperature. The most comprehensive understanding of the cold rolling parameters for both side-cladded materials was achieved by combining predictions for cladded and uncladded materials. The thickness of the cladded layer presented as a percentage after roll bonding was 18.7%. During the cold rolling and annealing, the cladded thickness was increased to 24.7% of the final 0.3 mm of the total cold-rolled product thickness. According to the performed braze test for final thickness, the ultimate tensile strength and yield strength were decreased, and the elongation increased to 18.1%. In addition to the described changes in mechanical properties, the material’s anisotropy improved from 5.4% in the cold-rolled condition to 2.0% after the braze test. After multiple re-meltings of the cladded material, the analyzed chemical compositions allow for recycling and reuse as different 4xxx, 5xxx, and 6xxx alloys.
