Why you need take forged wheel instead of cast wheel?
Forged wheels are less porous than cast wheels because of the forging process. The forging process makes these wheels stronger, more durable and more resistant to corrosion and oxidation. Additionally, the wheel's structural integrity is not compromised. Forged wheels tend to have greater overall vehicle performance and enhanced fuel efficiency.
ADVANTAGES IN COMPARISON TO CAST ALLOYS
Lightweight forged wheels offer a number of advantages compared to cast alloy alternatives. These include:Better fuel efficiency (by up to seven percent);Reduced CO2 emissions;Improved safety;Longer life for suspension components and brakes;Not to mention a more comfortable ride.LIGHTER
Forged wheels are approximately 20 percent lighter than cast alloys, and twice as light as steel wheels in weight, along with incomparably higher vibration absorption characteristics.
Ultra-light forged wheels stand out as a separate category representing best-in-class automotive products. These are predominantly used by professionals in high-end racing/motorsports competition series. These are also selected by car enthusiasts worldwide thanks to their significant weight reductions and other important benefits.
Wheels produced by real net-shape forging technology are extremely strong, durable and, therefore, safe because of the high degree of metal deformation (compaction) and non-existence of typical casting defects, such as cavities and cracks. This is achieved with a properly aligned fiber structure of the aerospace grade alloy via a three-dimensional closed-die hot forging process in a hydraulic press of 10,000-15,000 tons of force and in conjunction with a special heat treatment. If subjected to sudden impact, a forged wheel does not crack and can be repaired if necessary.
Aside from being a third lighter than aluminium, forged wheel has high specific heat values; 23 times higher than steel. Thus, intrinsic material characteristics ensure faster heat dissipation from the wheels and brake system, thereby prolonging the lifetime of brakes and brake pads. In addition, they represent an important safety factor.
Forged wheels also possess an exponentially higher damping factor providing for efficient absorption of vibrations, shocks, impacts and noise thus resulting in a significantly more comfortable ride for the driver and passengers and preserving the suspension system for longer service.
