Summary:•The FSW process was successfully performed on fresh plates of 2524-T3 Al alloy.•Micro-adhesive wear and microhardness tests were performed on parental and welded specimens.•The FSW process enhances the wear resistance of the 2524-T3 alloy.•Microhardness is influenced by the dissolution and reprecipitation of strengthening precipitates. Friction Stir Welding (FSW) emerges as a compelling solid-state welding technique for aluminium alloy components used as aircfrat materials. Despite being a solid-state process and mitigating numerous solidification challenges, it retains its thermomechanical nature, affecting the material's microstructure and, consequently, its mechanical properties. This concise communication sought to assess the impact of the FSW process on the micro-adhesive wear and microhardness properties of the 2524-T3 alloy. The results showed that the FSW process was executed successfully on 2524-T3 aluminium alloy plates as well as the great influence of intermetallic particles on hardness and micro-adhesive wear.
