This paper presents a micro-alloying approach to develop new high-performance aluminum alloys to achieve an improved and optimized combination of strength, electrical conductivity, and thermal stability. The micro-additions create nanoscale strengthening precipitates which are distinct from the traditional strengthening phases, such as β-Mg2Si and Al3Fe, and have a much higher thermal stability and coarsening resistance. This study demonstrates this micro-alloying modification concept in 1000-, 6000-, and 8000-series aluminum conductor alloys and discusses their mass-production scalability by the continuous casting process.
