Itself has a lighter weight and better the dynamic balance of performance, so the more lightweight, higher reliability, higher in sealing; At the same time is a higher manufacturing costs, relative to a single simple modeling.   Forging hub is now the most advanced manufacturing aluminium wheel method. Forging hub has the advantage of high strength, higher security, high plasticity, light weight, good heat dissipation, fuel efficient, better control performance. As shown below: 1. Durable and more secure. The strength of the forging aluminum ring more than 1 to 2 times the cast aluminum ring, four to five times higher than ordinary iron ring. More solid, collision resistant, toughness and fatigue strength is superior to the casting wheel hub. Not easy rolling breakage and safer.
