When looking for wheel rims on eBay Motos, buyers may find that most ofthe listings are rims featuring "cast" wheels; only a few are "forged". So what is the difference between forged and cast rims? What makes forged rims so special that they are priced higher? The table chart at http://stores. ebay.com/MOTOFORGE/Forged-and-Cast-Wheel-Rims-Compare.html helps you to know more about the advantages of forged rims.

Forged and cast rims differe in terms of manufacturing process; just looking at the terms "forged" and "cast" gives you the basic idea. Forged rims are made from solid aluminum billets (ex: the material used by Motoforge is high quality 6601 T6 aluminum, which is utilized in producing aerospace products). Aluminum billets are heated (bt not melted) to allow hydralic pressure machines to forge them into shapes of wheels rims; afterwards, the rims are further processed on lathes. Cast rims, on the other hand, are made from aluminum melted into liquid form and then poured into molds for cooling. The stucture and strength of solid aluminum is by all means superior to that of liquid aluminum. Being produced with intense pressure, forged wheel rims are 3 times stronger than cast ones. In addition, forged rimcs are light (25~30% lighter than cast rims), impact-resistant and durable, which are musts for reducing the total weight of a car and lead to better fuel efficiency, longer brake system life and relatively safer driving.
