Compared with stampings, one die casting can often replace several parts. Die castings frequently require fewer assembly operations; can be held within closer dimensional limits; can have almost any desired variation in section thickness; involve less waste in scrap; are produceable in more complex shapes and can be made in shapes not producible in stamped forms. Stampings, on the other hand, have properties of wrought metals; can be made in steel and in alloys not suitable for die casting; in their simpler forms, are produced more rapidly; and may weigh less than die castings.
