Abstract
Improved aluminum casting alloys having vanadium are disclosed, The new alloys generally include from 4,0 to 10.0 wt. % Si, from 0.01 to 0.15 wt. % V, and up to 0.10 wt. % Fe, among other elements. The improved aluminum casting alloys may realize, for example, improved strength and/or elongation properties.
