1. Fuel effort

On average, each aluminum alloy wheels are 2kg lighter than steel wheels of the same size. A car can not save 10kg weight with 5 wheels. According to Japan’s experiments, every 1kg of the five-seater car is 1kg, which can save about 20L gasoline each year. The research report published by the American Automotive Engineer Society pointed out that although aluminum alloy wheels are more expensive than ordinary steel wheels, when each car runs to 20,000 kilometers, the saved oil cost is sufficient to cover costs.

2. Increase the engine life

According to the engine load and power curve, when the load increases to a certain degree, its power will be reduced, and the amount of margin means that at this time, the engine’s requirements for each unit load will be higher (especially fuel consumption), and the engine load will be higher. Decreased, naturally reduce failure and extend life.

3. Good heat dissipation

The heating coefficient of aluminum alloy is three times that of steel. The heat dissipation effect is good. When the long -distance high -speed driving, the tire can maintain the appropriate temperature, so that the brake drum and tires are not easy to aging, extend the service life, and reduce the chance of explosive tires.

4. Good roundness

The accuracy is as high as 0.05mm, and the driving balance performance is good, which is conducive to eliminating the length of the body and the trembling of the steering wheel.

5. Strong and durable

The anti-impact performance, tensile strength and thermal strength of the aluminum alloy wheels are higher than the steel wheels. This is also one of the reasons why the aluminum alloy occupies an important position in the defense industry and the aviation industry.

6. Beauty

Due to the limitation of production, the general steel wheels are monotonous and lack of changes; the design of aluminum alloy wheels is diverse, coupled with good gloss and color effects, thereby increasing the value and aesthetics of the car.
