Aluminum alloys are divided into the wrought and cast categories according to how they are produced. The wrought category includes rolling, extruding, drawing, forging, and a number of other more specialized processes. Cast alloys are poured molten into sand (sand casting) or high-strength steel (permanent mold or die casting) molds where they solidifies to produce the desired shape.
