| Abstract Scope |
About one third of the annual aluminum production is contributed by the recycling of scraps. The stare alloy classifications and the difficult removal of foreign elements make the way of downcycling favorable. The product in this case is a secondary cast alloy which is mainly used in the internal combustion engine. The global trend toward electric vehicles shrinks the demand for those alloys and future vehicle scrapping may lead to a surplus of scraps with high concentrations of foreign elements.
This work investigates the potential of two secondary cast alloys EN-AC-46000 and EN-AC-46300, both on laboratory scale, for their use as wrought alloys The alloys were heat treated and successfully rolled to sheets. Mechanical tests comprised tensile tests in solution-annealed and artificial aged condition and hardness tests during the natural aging. The results show a promising combination of mechanical properties that can lead to an application as sheet material. |
