| Abstract Scope |
Lithium–aluminum alloys attract attention for their low density, high strength, and corrosion resistance. The Al–Cu–Li alloy system improves stiffness and reduces weight, but lithium’s high cost and reactivity pose challenges. Large amounts of scrap are generated during production, and recycling remains limited due to lithium oxidation and contamination from other alloying elements. During melting, lithium readily reacts with oxygen, causing composition loss and defects. Effective recycling requires melt protection, minimized containment, and controlled casting. This study aims to develop a sustainable method to synthesize Al–Cu–Li alloys from urban scrap materials using a specially designed furnace while minimizing lithium loss. |
