Comparative advantages of automotive aluminum alloy wheels and steel wheels

Release time:2020-10-20


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 of weight with 5. According to Japanese experiments, a 5-seater car can save about 20L of gasoline a year for every 1kg weight reduction. And the United States The research report published by the 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 savings can be enough to cover the cost.

2. Increase engine life
According to the engine load and power graph, when the load increases to a certain level, its power decreases. This margin will mean that for every unit load at this time, the engine will be more difficult (especially fuel consumption), and the engine load will be reduced. Naturally reduce failures and prolong life.

3. Good heat dissipation
The thermal conductivity of aluminum alloy is 3 times that of steel. The heat dissipation effect is good, and the tires can be kept at an appropriate temperature during long-distance and high-speed driving, so that the brake drum and tires are not easy to age, increase the life span, and reduce the chance of puncture.

4. Good roundness
The accuracy is up to 0.05mm, and the running balance is good, which is helpful to eliminate the general body length and steering wheel jitter.

5. Rugged and durable
The impact resistance, tensile strength and thermal strength of aluminum alloy wheels are higher than steel wheels. This is one of the reasons why aluminum alloys play an important role in the defense industry and aviation industry.

6. Beautiful
Generally, steel wheels are monotonous in form and lack changes due to production constraints; aluminum alloy wheels have a variety of designs, plus gloss and color effects, which enhance the value and beauty of the car.
