“…The control of impurities has a major influence on the mechanical properties of recycled alloys. Similarly, Mansurov et al 19 mentioned that recycling causes the addition of impure elements, such as Si, Fe, Cu, Zn, Pb, Sn, Ni, and Mn, in the alloy casting properties. Another relevant factor, especially during the casting process, is that scrap from urban recycling is generally oxidized.…”

“…17 Recycling aluminum alloys has grown in interest and applications in recent years and has become an economical, environmentally friendly, and reliable way to produce aluminum parts. 18 Also, according to Mansurov et al., 19 besides aluminum's high resistance to corrosion and excellent recyclability, the relatively low market value of foundry technology provides a larger share of the demand for aluminum alloys.…”

This research experimented with different aluminum can casting compositions from recycled materials. The objective was to analyze the casting yield and the resulting chemical compositions of the process. In the first process, 20 kg of aluminum cans was melted, resulting in a 10.2 kg ingot, which presented a 51% yield. In the second process, 10 kg of 6063 T6 aluminum was used and 10.2 kg of the first casting was added. This mixture produced an ingot of 50% recycled aluminum and 50% 6063 aluminum that weighed 18.23 kg. Similarly, a second ingot was produced, but with the addition of 4 wt% of rice husk ash and 2 wt% of magnesium. From each ingot, the samples were removed for chemical analyses, which consisted of tests of the samples that had the incorporation of rice husk ash in the molten aluminum. These analyses included scanning by electron microscopy, density analysis, Brinell hardness, and Charpy impact force tests. The results of the second ingot analysis showed superior characteristics in Si and Mg levels due to the addition of rice husk ash and magnesium. Also, the second ingot presented increased hardness as well as a reduction fragility and density.

“…The control of impurities has a major in uence on the mechanical properties of recycled alloys. Similarly, Mansurov et al (2018) mention that recycling causes individual and combined addition of impurity elements, such as Si, Fe, Cu, Zn, Pb, Sn, Ni and Mn, in the alloy casting properties (DAGWA; ADAMA, 2018). Another relevant factor, especially during the smelting process, is that scrap from urban recycling is generally oxidized.…”

This research presents a methodology for the recycling process via casting, in which aluminum cans and primary (commercial) aluminum are transformed into a laminated tape, with the possibility of industrial application. This research was classified as bibliographic, exploratory, and experimental, since it used qualitative techniques to evaluate alternative materials. Its objective was to incorporate materials of different properties that could favor the making of a tape to be laminated. In the first casting, a recycled aluminum ingot was formed only with aluminum from beverage cans and had a material yield of 51%. In a second casting, commercial aluminum was added to the recycled aluminum ingot. After the casting process with the two cast materials, the ingot had a yield of 90%. A third casting was conducted together with the aluminum that was already formed by the ingot (50% recycled and 50% commercial). The purpose of this ingot was to incorporate other materials that could provide some characteristics, such as malleability and conductivity. The third casting was made from the second ingot, and incorporated copper and magnesium. For the design of the laminated tape, a cast was made to receive the molten aluminum from the third casting. The aluminum was cast into this mold and three tapes were produced, one with a thickness of 2 mm, another with a thickness of 3 mm and the last with a thickness of 4 mm. With these tapes, the objective was to laminate them in order to reduce their thickness to values close to 0.5 mm. The casting process of aluminum cans with the addition of commercial aluminum, plus the incorporation of copper and magnesium, demonstrated facilities for thickness reduction in the process of making laminated tapes.
