How many years can automotive aluminum alloy wheels last???

The owner's "pursuit" of the appearance of the car and the "chasing stick" of the aluminum wheel hub are due to its fashionable appearance, diverse styles, and its unique high vibration resistance, heat transfer and thermal conductivity, changeable wheel spokes, and unique spraying process or coating process. Gradually in modern cars.

It has been widely popularized and applied in the direction of development.

Regarding the service life and maintenance, it mainly depends on the maintenance of the daily use process, the driving environment and whether the vehicle wheel hub including other related parts are maintained in a timely manner according to some requirements or standards in the "User Manual".

Under normal circumstances, because of its special production process and related industry standard specifications, in terms of safety and security scope, it is no problem for about 50 years, but it is not absolute, and over time, it will gradually "degrade" in terms of vibration resistance, elastic toughness, heat conductivity, comfort, etc.

In the process of use, no matter how long it has been used, routine maintenance and maintenance are indispensable. When a variety of "phenomena" such as "fault" or deformation, missing, aging cracks, and broken pairs caused by accidents are found, they should be replaced in time to ensure driving safety.

Attached: Features of aluminum alloy wheels.

a. Fuel saving: the density of aluminum is smaller than that of steel, and the moment of inertia.

Small, the acceleration performance of the car is improved, and the braking performance is also improved, which improves the acceleration ability of the car and saves fuel.

b. High safety: due to forging, it is not easy to deform and disperse temperature quickly, so the impact on the tire is greatly reduced; At the same time, the higher and hardness characteristics of aluminum alloy wheels significantly reduce the influence of "pressure" and "deformation" on the wheel hub when driving, especially when cornering, and improve the safety of driving to a certain extent.

c. Comfort: The aluminum alloy hub is a precision casting, with little roundness and unbalance, good vibration resistance, and can reduce the vibration during driving. It has an energy-absorbing or buffering effect.

d. Heat dissipation transmission: high temperature caused by friction between brake discs and brake pads, aging and wear of tires and brake pads. With that comes a drop that affects the braking effect!

In actual traffic conditions, it is not uncommon for tire bursts and brake failures to occur due to "high tire pressure". It is precisely because of the characteristics of aluminum alloy wheels (good heat dissipation transmission and fast speed) that to a certain extent, it alleviates or reduces the accidents that occur during high-speed operation, such as "puncture" accidents, making driving safer.

I don't know what car the landlord bought? The wheel hub is not calculated by years, it is generally calculated by the number of kilometers traveled, and it is generally not a big brand of wheels that run normally for 25-300,000 kilometers without any problem, but you had better replace the 4 wheels with each other every 8-100,000 kilometers, so that the force is more uniform in all aspects and the life is longer.

Now aluminum alloy wheels are already the mainstream, aluminum alloy is good-looking, light, and has good heat dissipation. If there is no external damage, it will be about 5 years. When exactly to change it, the 4S store will tell you when you go for maintenance.

The better the aluminum rim is used, the longer it is, and the cheaper it can also be used, but in the case of receiving an external impact, it is different from the poor quality, the good bearing capacity is strong, and the life is generally very long, as long as the ring edge is not worn down, you can continue to use, it is recommended that you use the vertical wheel, and the manufacturer guarantees 3 years.

Hello, there is no fixed cycle, if it is broken, it will be replaced.

Regarding the landlord's concern about "how about aluminum alloy wheels?" "Here's my personal opinion:

Aluminum alloy wheels are still good, and the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels. Advantages of aluminum alloy wheels:

1. Compared with steel automobile wheels, the advantages of aluminum alloy wheels are more obvious: the density is small, about 1 3 of steel, which means that the use of aluminum alloy wheels of the same volume will be lighter than steel wheels 2 3, statistics show that the quality of the car is reduced by 10%, and the fuel efficiency can be increased by 6% 8%, so the promotion of aluminum alloy wheels is of great significance for energy conservation and emission reduction, and low-carbon life;

2. The thermal conductivity of aluminum is high, while the thermal conductivity of steel is low, so under the conditions of Tongqing Turbulence, the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels;

3. Fashionable and beautiful, aluminum alloy can be aged, the aluminum alloy wheel casting billet without aging treatment has low strength, easy to process and form, and the aluminum alloy wheel after corrosion resistance treatment and coating and coloring is diverse, exquisite and beautiful.

There is no need. Aluminum alloy wheels have a slightly shorter life than steel wheels, and aluminum alloy wheels are actually stiffer than steel wheels. Therefore, under the same strength, the energy absorption is not as good as that of steel wheels, and it is more likely to break.

1. Fuel saving: On average, each aluminum alloy wheel is 2kg lighter than steel wheels of the same size

5 cars can save a lot of 10kg. According to Japanese experiments, the weight of a 5-seater car is reduced by 1 kg

About or save 20L of gasoline a year. A research report published by the Society of Automotive Engineers pointed out that although aluminum alloy wheels are more expensive than ordinary steel wheels, the fuel cost saved by each car is enough to cover the cost when it runs to 20,000km. 2. Increase engine life.

According to the engine load and power curve, when the load increases to a certain extent, its power decreases, and this margin will mean that for every 1 unit load at this time, the engine will be more strained (especially fuel consumption), the engine load will be reduced, and the failure will be naturally reduced and the life will be prolonged. 3. The thermal conductivity of aluminum alloy is 3 times that of steel. The heat dissipation effect is good, and the tires can also be kept at the appropriate temperature when driving at high speed for long distances, so that the brake drum and tires are not easy to age, increase the life and reduce the chance of puncture.

4. Good roundness and high accuracy.

It has good running balance performance, which is conducive to eliminating the phenomenon of over-length of the general body and steering wheel shake. 5. The impact resistance, tension resistance and thermal strength of sturdy aluminum alloy wheels are higher than those of steel wheels. This is also one of the reasons why aluminum alloy plays an important role in the defense industry and aviation industry.

6. Aesthetic general steel wheels are monotonous and rigid due to production limitations, and lack of change; Aluminum alloy wheels have a variety of designs, plus gloss, color effect is good, thus improving the value and beauty of the car.

Summary. Dear, I'm glad to answer for you! Replacing steel wheels with aluminum alloy wheels will improve the appearance, performance and comfort of the vehicle to a certain extent, but whether to replace them depends on individual needs and usage.

Aluminium wheels are lighter, which reduces the weight of the vehicle, which in turn reduces fuel consumption and pollutant emissions. In addition, the aluminum alloy material has good thermal conductivity, which has a good heat dissipation effect at high speed, which helps the heat dissipation of the tire, thereby prolonging the life of the tire. In addition, aluminum alloy wheels also have good wear and corrosion resistance and long service life.

However, aluminum alloy wheels are higher than steel wheels, and they are relatively more likely to be damaged. Aluminum alloy wheels are also easy to absorb dust, so it is recommended that car owners need to clean and protect them frequently to maintain the beauty and <>energy of the wheels

Is it necessary to change the steel wheels to aluminum alloy wheels?

Dear, I'm glad to answer for you! Replacing steel wheels with aluminum alloy wheels will improve the appearance, performance and comfort of the vehicle to a certain extent, but whether to replace the ear cavity depends on individual needs and usage. Aluminium wheels are lighter, which reduces the weight of the vehicle, which in turn reduces fuel consumption and pollutant emissions.

In addition, the aluminum alloy material has good thermal conductivity, and has a good heat dissipation effect in high-speed driving, which helps the heat dissipation of the tire, thereby prolonging the life of the tire. In addition, aluminum alloy wheels also have good wear and corrosion resistance and long service life. However, aluminum alloy wheels are higher than steel wheels, and they are relatively more likely to be damaged.

Aluminum alloy wheels are also easy to absorb dust, so it is recommended that car owners need to clean and protect them frequently to maintain the beauty and <>energy of the wheels

The characteristics of steel wheels and aluminum alloy wheels are expanded for you: 1Steel wheels are relatively inexpensive, durable, and easy to maintain, making them suitable for affordable family vehicles or commercial vehicles with larger loads.

However, steel wheels are heavier, which affects the vehicle's suspension system and fuel economy, and the appearance is not as stylish and beautiful as aluminum alloy wheels. 2.Aluminum alloy wheels are relatively lightweight, which can improve the suspension system of the car and reduce the fuel consumption of the vehicle.

In addition, the appearance of aluminum alloy wheels is fashionable and beautiful, which can enhance the quality of the whole vehicle. However, the aluminum alloy Jianye wheel** is relatively high, difficult to maintain, and easy to be damaged <>

There is no need to change the steel wheels to the aluminum alloy wheels.

Under the premise of the same weight, although aluminum alloy wheels are more impact-resistant, steel wheels are more flexible. The impact force that can deform the steel wheels may not deform the alloy wheels, because the alloy wheels are thicker. However, after the impact force is large to a certain extent, the aluminum alloy wheel can be directly cracked, while the steel wheel is only more seriously deformed.

It is generally believed that aluminum alloy wheels are lighter, but aluminum alloy wheels are very large in order to ensure strength. Therefore, on the whole, traditional aluminum alloy wheels are not necessarily lighter. Those high-end forged steel wheels, due to the increased strength of the forging process, can be made smaller, which can also reflect the weight advantage.

Therefore, based on comprehensive analysis, there is no need to replace steel wheels with aluminum Hongming alloy wheels.

The difference between steel wheels and aluminum alloy wheels:

1. Different models of application: In ordinary life, the wheels used by large trucks, trucks and other relatively large vehicles are steel wheels, while most of the current family cars and SUV models use aluminum alloy wheels, which is because the application is more beautiful and looks more atmospheric in family cars.

2. Different weight: Because aluminum alloy is relatively light, the weight of the wheel hub is lighter than that of steel wheels.

3. Different heat dissipation performance: because the aluminum alloy wheel has the advantage of fast heat dissipation, it can quickly consume the heat generated by the car when braking, prolong the service life of tires and braking systems, and reduce the probability of wheel puncture. The heat dissipation of steel wheels is not as good as that of aluminum alloy, because the heat dissipation of steel elements is relatively slow, and the heat generated by the car is often still stored in the tires.
