| Abstract Scope |
High strength aluminum sheet is increasingly used for vehicle lightweighting, but conventional grades have very high carbon footprint. This work aims to develop a high strength 6xxx aluminum sheet with significantly reduced carbon footprint through three strategies: (1) maximizing scrap usage to minimize dependency on primary aluminum, (2) using twin-roll casting to eliminate slab homogenization and hot rolling, and (3) integrating partial solutionizing treatment of 6xxx sheet in hot stamping process. Industrial-scale twin-roll cast 6xxx coils were successfully produced and cold rolled to 1-2 mm for various hot stamping trials, including door inner panels, battery trays and cold plates. After hot stamping and artificial aging, the material achieved an ultimate tensile strength of 370 MPa with a total elongation of 10%. In addition to the reduced carbon emissions, these hot stamped components can also be manufactured at much lower cost than today's cold stamping of commodity 6xxx aluminum sheets. |
