Application of aluminum sheet in automobiles
Body, engine, panel, battery cover, etc.
With the development of the automobile industry, aluminum, as a lightweight material, is widely used in automobile manufacturing. Aluminum has excellent physical and chemical properties, which can meet the needs of automobile manufacturing, and can effectively reduce the weight of the vehicle and improve fuel efficiency.
Aluminum sheet for body structure:
Aluminum alloy is widely used in the body structure of automobiles. Compared with traditional steel, aluminum alloy has lighter weight and higher
strength. Aluminum plate for car can reduce the weight of the body and improve the fuel efficiency of the vehicle. At the same time, aluminum alloy also has high corrosion resistance, can withstand harsh environmental conditions, and extend the service life of the body.
Aluminum sheet for carEngine parts:
Aluminum alloy is also widely used in automobile engine parts, such as engine cylinder head, crankcase, etc. Compared with cast iron materials, aluminum alloy has better thermal conductivity and lower thermal expansion coefficient, which can improve the working efficiency and reliability of the engine.
Aluminum sheet for carSuspension system:
Aluminum alloy materials are also used in the suspension system of automobiles, such as suspension arms, suspension rods, etc. Aluminum alloy suspension parts have high strength and low weight, which can improve the response speed and handling performance of the suspension system, making driving safer and more comfortable.
Aluminum sheet for car Braking system:
Aluminum alloy has good thermal conductivity, so it is also widely used in braking systems. Aluminum brake calipers have low weight and good heat dissipation performance, which can improve the efficiency and stability of the braking system. In addition, aluminum alloy brake discs can also reduce vehicle weight and improve fuel efficiency.
Aluminum sheet for car Interior decoration: Aluminum alloy materials are also used in car interior decoration, such as dashboards, door handles, shift levers, etc. Aluminum alloy interior decoration has high decorativeness and low weight, which can improve the luxury and comfort of the car.
Why do cars like to use aluminum?
Aluminum, with its unique properties, has attracted widespread attention in the field of car body materials in recent years. The application of aluminum alloy car bodies not only improves the technical content of products, but also saves the cost of automobile manufacturing. So, compared with traditional steel, what are the advantages of aluminum sheet for cars? Why is Aluminum sheet used for car so popular in the market?
First of all, the lightweight effect of aluminum is significant.
Aluminum, with its lightness, is an ideal choice for lightweighting the vehicle body. Compared with steel, which has a density of 7.8g/cm³, the density of aluminum is only 2.7g/cm³, which is about 1/3 of steel. In automobile manufacturing, the weight of the vehicle body usually accounts for 30-40% of the weight of the whole vehicle. If steel is replaced with aluminum alloy, the weight of the whole vehicle is expected to be reduced by up to 40%, which is an advantage that is self-evident. Take the fourth-generation Range Rover as an example. This car was the first to introduce the concept of an all-aluminum body. Compared with the previous generation, its weight was reduced by nearly 40%, a total of 350kg, equivalent to the weight of 4-5 adult men. The lightweight body directly improves the vehicle’s power performance, fuel economy and handling stability.
Secondly, the aluminum body has higher strength.
Although steel is superior in absolute strength, aluminum alloy can also achieve excellent strength performance through reasonable thickness design. Since the density of aluminum is much lower than that of steel, aluminum alloy requires less material to achieve the same strength requirements, thus achieving a perfect combination of lightweight and high strength.
This also explains why aluminum alloy can show strength that exceeds that of steel under the same weight conditions. Take Xiaomi Su7 as an example. Its body torsional rigidity is even better than Volvo XC90, which is the unique charm of aluminum alloy materials.
In addition, aluminum plates have stronger corrosion resistance.
Aluminum easily forms a dense oxide film after contacting the air. This oxide film is closely combined with the matrix, providing effective protection for the aluminum. This allows aluminum bodies to show better durability in various severe weather conditions, such as rain and snow.
For car owners in wet and cold environments, the corrosion of snow melting agents on steel bodies is a problem that cannot be ignored. However, the use of aluminum alloy bodies can fundamentally solve this problem, so that car owners no longer need to worry about it.
In summary, the advantages of aluminum in body materials are obvious.
