The aluminum material is relatively light, which can reduce the quality under the shock absorber and ensure a good suspension reaction speed. There is also the good heat dissipation performance of aluminum.
1. Fuel saving
On average, each aluminum alloy wheel is 2kg lighter than a steel wheel of the same size, and a car can save 10kg in weight with 5.According to Japanese experiments, for every 1kg reduction in the weight of a 5-seater car, about 20L of gasoline will be saved in a year.A research report published by the American Society of Automotive Engineers pointed out that although aluminum alloy wheels are more expensive than ordinary steel wheels, when each car reaches 20,000 kilometers, the fuel savings will be enough to offset the cost.
2. Strong and durable
The strength of aluminum alloy wheels in terms of impact resistance, tension resistance and heat resistance is higher than that of steel wheels.This is also one of the reasons why aluminum alloy plays an important role in the national defense industry and the aviation industry.
3. Good true roundness
The accuracy is as high as 0.05mm, and the operating balance performance is good, which is conducive to eliminating the general long body and steering wheel jitter.
4. Good heat dissipation
The heat conduction coefficient of aluminum alloy is 3 times that of steel.The heat dissipation effect is good. During long-distance and high-speed driving, the tires can also be kept at the appropriate temperature, so that the brake drums and tires are not easy to age, increase life, and reduce the chance of a flat tire.
5. Increase engine life
According to the graph of engine load and power, when the load increases to a certain extent, its power decreases in reverse. This marginal value means that for every unit of load at this time, the engine will be more laborious (especially fuel consumption), and the engine load will be reduced, which will naturally reduce failures and extend life.
6. Beautiful appearance
Generally, steel wheels are limited in production, their form is monotonous and rigid, and they lack changes; aluminum alloy wheels have a variety of designs, plus good gloss and color effects, thereby improving the value and beauty of the car.
