Abstract Scope |
Using heat treatable aluminum alloys for structural applications, suitable for e-mobility applications, demands not only appropriate strength values but also a high formability of the material in the delivery condition T4, while exhibiting a sufficient age-hardening response at the industrial paint bake process.
To fulfill these OEM requirements, as part of this work a 6xxx (Al-Mg-Si) was developed, which shows high formability as of an outer skin alloy and achieves the required age-hardening response. Additionally, this alloy contains a higher iron content to allow for a higher scrap input to reduce the CO2 footprint to a minimum.
Key factor is the correct Si:Mg ratio and the cluster size stabilization after solution heat treatment in a fine-tuned pre-aging process. Mechanical properties and formability were tested and compared to a reference alloy used for outer skin applications. Results showed an improved forming behavior making the material suitable for e-mobility applications. |
