Scientists at Oak Ridge National Laboratory have advanced the use of DuAlumin-3D, an innovative aluminum alloy, in high-temperature automotive components, significantly expanding the possibilities of additive manufacturing.
The research team found that DuAlumin-3D outperforms traditional alloys, which are prone to cracking during laser powder bed fusion processing, while maintaining comparable heat characteristics. This advancement offers lightweighting solutions and reduces fuel costs.
Lead ORNL researcher Alex Plotkowski said, “DuAlumin-3D performed exceptionally well in our evaluations. While our research focused on its use in high-efficiency engines, it could also be used for lightweighting applications in aerospace and to optimize heat exchangers.”
The ORNL-developed alloy exhibits superior strength and resistance to deformation at elevated temperatures, outperforming all known aluminum alloys.
