Abstract Scope |
In recent years, demands for increased lightweight performance and lowered fuel consumption in automobile body in white structures have been growing. Cosma, the body and chassis group of Magna International, initiated a research program dedicated to developing an optimized low-cost aluminum alloy for structural high pressure vacuum die cast automotive components. For most high vacuum die cast applications, the mechanical properties are one of the most important requirements. Ductile properties are specified to ensure crash behavior and rivetability for joining purposes. This research program is comprised of both theoretical and experimental elements to arrive at a self-hardening Aural 5M (modified) alloying system that satisfies the desired mechanical properties in as-cast (F-temper) condition. In addition, for manufacturability of the next generation of ultra large body castings, new aluminum alloys are also required to exhibit enhanced castability. This paper discusses the improved properties and manufacturability of Magna’s new Aural 5M alloy. |
