Aluminum alloys that contain dilute scandium additions display upgraded properties in several areas. In conjunction with zirconium, scandium forms very fine, coherent precipitates that impart strength and serve to inhibit recrystallization in aluminum alloys. In addition, these alloys display improved hot-cracking resistance during welding, and enhanced weld strength. Several scandium-aluminum alloys are currently under development, and some of the more interesting properties are presented in this article.
