5182 Aluminum Plate VS Steel Plate, Which kind of car hood material is better?

The hood is an important part of the car. In cars, the hood plays an important role in protecting the engine and peripheral components, assisting driving vision, reducing airflow effects, and preventing accidents. The design of the hood is also an intuitive manifestation of vehicle value. At present, the automobile hood on the market is made of aluminum alloy and steel plate, and aluminum alloy is mostly 5182 aluminum plate. Which of these two materials is better?



The material of the hood of the car requires high energy absorption capacity and weak strength to ensure the safety of pedestrians in an emergency. The aluminum plate absorbs twice as much energy as the steel plate, which is beneficial to reduce the damage of the car to the pedestrian's head during the collision process, and has a good protection for pedestrians.

At present, more and more car manufacturers use the 5182 aluminum alloy to make the car hood. The main reasons are as follows:

1, 5182 aluminum plate stamping effect is good, processing performance is good. The 5182 alloy sheet can be used for the door, hood and front and rear fenders of the car. From the market feedback, the processing performance and stamping effect of the 5182 alloy aluminum plate performed well, and the aluminum plate was punched without cracking.

2, 5182 aluminum plate is light in weight and can reduce the weight of the car. The density of aluminum is about 1/3 of that of steel plates. It is also used to make automobile hoods. It can reduce the car's own weight and fuel consumption, reduce environmental pollution, and follow the development trend of automobile lightweight while ensuring the safety performance of automobiles.

3. Aluminum alloy has high recovery, energy saving and environmental protection.
