Abstract

The present research focuses on the recycling of various aluminium scraps that contain significant levels of silicon, iron, manganese, and copper to create a new aluminium alloy with superior properties. The alloy was designed to exhibit high extrudability and mechanical properties. The alloy was extruded at a low temperature of 430 °C, resulting in a good yield and form free of extrusion flaws. The produced alloy was characterized in three sets: Set 1 without aging (0 h), Set 2. with different aging times (3, 4, and 5 h) at 185 °C, and Set 3. with heat treatment and different aging times (3 h., 4 h., and 5 h.). The mechanical, electrical, and microstructural properties of each set were investigated. The samples in Set 1. had poor mechanical properties but high ductility due to the presence of Cu-enriched intermetallic as the dominant phase. Set 2 samples had the best mechanical properties while preserving high ductility, which was due to the synergy between α-Al (FeMn) Si, Cu-enriched intermetallic, spheroidal AlCuMgSi, and modified silicon particles. Set 3. samples underwent heat treatment at an elevated temperature (530 °C for 3 h) with rapid quenching, then aged for varying times and quenched rapidly, this led to the dissolution of the Cu-enriched intermetallic except for the AlMgCu phase with (Al₉₆Mg₃Cu₁ and Al₉₄Mg₅Cu₁, at. %), and the dominant phase was α-Al (FeMn) Si phase, which improved mechanical characteristics. Overall, the ASH01 alloy produced in Set 2 conditions is a promising alloy with strong mechanical characteristics and ductility as a recycled Al-scrap alloy.
