Abstract
A cast aluminum alloy vehicle wheel has a central disk, a rim, and a rim carrying portion located between the rim and the central disk. The rim has an end or tip portion that is the farthest portion of the rim from the disk, and a barrel portion is located between the rim carrying portion and the rim end. The microstructure of the metal provides a dendritic arm spacing (DAS) that is smaller at the rim end than at the rim barrel. Additionally, the DAS of the barrel portion is less then at the central disk. The DAS of the rim carrying portion is equal or less then the DAS of the barrel portion on the rim. A high strength wheel is provided, especially at the rim.
