Sand Casting - an overview ScienceDirect Topics

Sand castings are less common in structural applications, due to their slower cooling rate and generally coarser microstructure. However, in certain applications, such as the cast 356-T6 nodes for the Ford GT spaceframe, need for specific geometries at low production volumes requires the use of sand castings.
