Forging aligns the granular structure of the metal in a way that makes for a stronger more ductile wheel. Do not confuse forging with hardness, brittleness etc. Those are functions of the anealing process employed.

A quality forged wheel will withstand higher impacts than a cast wheel without shattering/deforming. Because of that, it can be made consideralbly lighter for a given use or considerably stronger for a given weight. This is why knives and axe heads (for example) are forged, not cast.

The equipment and labor needed to create forged wheels is considerably more expensive than cast technology > hence higher cost.

Flow forming and other "intermediate" technology is a means to bring "some" of the benefit of forging at "some" of the cost.

The BBS web site has some interesting information if you are interested.

Have fun.
Exactly right, couldn't have said it better.
