| Abstract Scope |
Aluminum 3xxx series alloys, particularly 3003, are widely used for automotive radiator applications due to their excellent formability and corrosion resistance. This study focuses on developing an improved 3003-type alloy produced via continuous casting using high-percentage recycled (scrap-based) feedstock. An optimized alloy design was proposed to compensate for compositional variations inherent in scrap recycling, targeting improved castability and mechanical properties while maintaining cost advantages. Thermodynamic and kinetic simulations were conducted to analyze phase formation, segregation behavior, and solidification dynamics under continuous casting conditions. Pilot-scale casting trials were performed to validate the alloy design, followed by mechanical property evaluations including tensile strength and elongation. Results demonstrate that tailored alloy chemistry combined with controlled continuous casting can produce radiator-quality sheet with properties comparable to or exceeding conventional 3003 alloys, supporting more sustainable and cost-effective manufacturing for automotive heat exchanger applications. |
