Among the various steps of aluminum production from liquid metal, a lot of scrap is generated due to machining operations. Therefore, recycling of aluminum scrap is an interesting subject because of the broad applications of this metal and low efficiency of processes used to recycle metal scrap. In this article, the recyclability of aluminum alloy AA 336 turnings with different cold compacting pressure and protective salt flux (NaCl-KCl-KF) has been experimentally studied. Various categories of compacted samples have been melted at 750°C in molten aluminum alloy AA 336 and in some experiments in the protective salt flux to recover aluminum alloy. Weight loss of all samples has been measured. It is shown that using protective salt flax is the best route, from the point of view of recyclability. Mechanical properties and chemical analysis of samples approximately are the same as the primary material produced by conventional casting process. Copyright © Taylor & Francis Group, LLC. Source
