FORGED WHEELS VS CAST ALLOY WHEELS

LIGHTER
Forged wheels are approximately 20 percent lighter than cast alloys, and twice as light as steel wheels. Forged magnesium wheels provide a further 25 percent reduction in weight, along with incomparably higher vibration absorption characteristics.To get more news about Alloy rims, you can visit nnxwheels.com official website.

Ultra-light forged magnesium wheels stand out as a separate category representing best-in-class automotive products. These are predominantly used by professionals in high-end racing/ motor sports competition series. These are also selected by car enthusiasts worldwide thanks to their significant weight reductions and other important benefits.

STRONGER
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.

LONGEVITY
Aside from being a third lighter than aluminium, magnesium has high specific heat values; 100 times higher than aluminium and 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.

Magnesium 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.

COMPARED TO CAST MAGNESIUM, FORGED MAGNESIUM WHEELS ARE STRONGER
Forged magnesium wheels are in an entirely different category; they have a higher specific strength value and toughness (ability to absorb energy) compared to a cast magnesium wheel. It is hardly surprising that forged magnesium wheels are selected by car and motorcycle enthusiasts worldwide given that they are 15 – 20 percent lighter than vintage magnesium wheels and even stronger than cast motor sport wheels.

IMPROVE BRAKING PERFORMANCE
As competition wheels are subjected to speeds of over 300 km/hour, safety is a top priority. Magnesium wheels provide faster heat dissipation from both the wheel and brake system – an important factor for motor sports professionals. Excessive heat is detrimental to tire life cycle, braking performance and brake pad life. Magnesium alloys enjoy a higher specific heat value.

PROLONG THE SERVICE LIFE OF THE SUSPENSION SYSTEM
Magnesium wheels also possess a higher damping factor, allowing for a number of improvements, such as better absorption of vibrations, shocks, impacts and noise thereby prolonging the service life of the suspension system. These features are important not only for race wheel applications, but also for mainstream driving comfort and improved fuel economy.
