Q: Why are forged wheels worth the extra cost over cast?

Forging applies enormous force to shape heated 6061-T6 billet, which refines the grain into a fine, uniform, directional flow. That reduces internal voids, so forged aluminum is less prone to cracking under stress than a cheaper, heavier cast wheel, and it deforms rather than fractures when you hit a pothole at speed. Higher tensile strength and toughness are the payoff. UP Forged wheels typically outlast the vehicle.
