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. The first advantage of aluminum alloy wheels is their light weight. The advantages of light weight are clear: fuel utilization is improved, cars are accelerating, and braking functions are improved.
According to the Japanese experiment, the weight of the five-seat car is reduced by 1kg, and about 20L of gasoline is saved in one year. The research report announced by the American Society of Car 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 return the cost. Fuel utilization is improving, cars are accelerating, and braking functions are improving.
2, add 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 laborious (especially fuel consumption) and the engine load will be reduced every 1 unit load. Naturally cut down the problem and extend the lifespan.
3, good heat dissipation
The heat transfer coefficient of aluminum alloy is three times that of steel. The heat dissipation effect is good, and the tire can be kept at the proper temperature when the vehicle is traveling at a high speed, so that the brake drum and the tire are not easily deteriorated, and the life is increased to reduce the timing of the tire blow.
4, good roundness
The precision is up to 0.05mm, and the running balance function is good, which is beneficial to eliminate the excessive length of the body and the 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.
