Analysis and comparison between forged aluminum wheel and steel wheel ：

    1.Light weight. The weight of forged aluminum wheel is only half of that of steel wheel. Taking 22.5x8.5 as an example:  the weight of forged aluminum wheel is 24 kg, and that of steel wheel is at least 49 kg.

2.Fuel economy.  Forged aluminum wheels are lighter in weight, which easily increase accelerating performance and decrease braking energy demand, and correspondingly save fuel.  In addition, due to the unique air flow and rolling resistance of forged aluminum wheel, the fuel saving rate of 100 km test is at least 2 liters per 100 km (The fuel consumption of the former is 2.5 liters lower than that of the latter).

3.Tire wear is reduced by 26%. Because of the characteristics of the forged aluminum wheel, its equilibrium value is 0, it is not easy to deform, and it has fast temperature dispersion (the normal driving temperature is 20-30 degrees lower than that of the steel wheel). It has better protection for the suspension system, so the wear of the tire is greatly reduced, making each tire run 50000-80000 km more).

4.Can reduce the maintenance cost of brake.Forging aluminum wheels are characteristic of quick heat dissipation,so can well protect braking system and parts which are made of materails not quite resistant of high temperature,hence greatly reduce the maintenance cost of brake system.

   5.Higher loading capacity. The bearing capacity of the forging aluminum wheel  is 5 times that of the ordinary steel wheel. The forged aluminum wheel only deforms 5cm after bearing 71200kg when the steel wheel has been deformed 5cm after bearing 13600kg.  In other words, the strength of forged aluminum wheel is five times higher than that of steel wheel. 

6.Improve driving comfort. Because of the characteristics of forged aluminum wheels, the driving experience after installation is lighter, and the high-speed driving is particularly smooth, so as to improve the driving pleasure.

7.Safe. For high-speed vehicles, it is not surprising that high-temperature tire burst and braking efficiency decrease due to tire friction and braking. The heat transfer coefficient of aluminum wheel is three times that of steel. Because of the layout characteristics of aluminum wheels, it is easy to disperse the heat generated by tires and chassis in the air. Even in the environment of long-distance high-speed driving or continuous braking on downhill road, the car can be connected to the appropriate temperature. It can not only make the drum of tire and brake not easy to be aged due to high temperature, but also reduce the tire burst rate.

8.Have a higher strength of resistence. When under the same impact of external force, forged aluminum wheels suffer far less damage than steel wheels.

9.Nice appearance. The forging aluminum wheel has a large degree of freedom in appearance design, which can connect the car with the wheel and make it perfect.
