Advantages of aluminum alloy wheels
1, fuel economy
On average, each aluminum alloy wheel is 2kg lighter than a steel wheel of the same size, and 5 cars for one car can save 10kg. According to the Japanese experiment, the weight of a 5-seat car is reduced by 1kg, and about 20L of gasoline is saved in one year. The 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 runs to 20,000 km, the fuel cost saved is enough to offset the cost.
2, increase engine life
According to the engine load and power curve, when the load increases to a certain extent, its power will decrease. This margin will indicate that the engine will be more difficult (especially fuel consumption) and the engine load will be reduced every 1 unit load. Naturally reduce malfunctions and extend life.
3, good heat dissipation
The heat transfer 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 be kept at an appropriate temperature, so that the brake drum and the tire are not easily deteriorated, the life is increased, and the chance of the puncture is reduced.
4, good roundness
Accuracy of up to 0.05mm, good running balance performance, is conducive to eliminating the general body length and steering wheel jitter.
5, sturdy and durable
The impact strength, tensile strength and thermal strength of the aluminum alloy wheel hub are higher than those of the steel wheel hub. This is one of the reasons why aluminum alloy plays an important role in the defense industry and aviation industry.
6, beautiful
Due to the limited production, the general steel wheel is monotonous and lacks change. The aluminum alloy wheel has a variety of designs, plus gloss and color effect, which enhances the value and beauty of the car.
