| Abstract Scope |
The present research focuses on the recycling of various aluminium scrap that contains significant levels of silicon, iron, manganese, and copper to create a new aluminium alloy with superior properties. The designed alloy exhibited high extrudability and mechanical properties. The alloy was extruded at a low temperature of 430 C, giving a good yield and form free of extrusion flaws. The produced alloy was characterized in three sets: Set 1 without aging (0hr.), Set 2. with different aging times (3hr., 4hr., and 5hr.) at 185 C, and Set 3. with heat treatment and different aging times (3hr., 4hr., and 5hr.). The mechanical, electrical, and microstructural properties of each set were investigated. Set 2 samples showed the best mechanical properties while preserving high ductility due to the synergy between α-Al (FeMn)Si, Cu-enriched intermetallic, spheroidal AlCuMgSi, and modified silicon. Recycling Al-scrap can assist to minimize global warming since it emits less GHG. |
