What Are Advantages and Disadvantages of Aluminium Car Bodies

Aluminum alloys achieve an ideal balance of strength, lightness and recyclability. The use of automotive aluminum sheets can effectively reduce the overall weight of the car, improve fuel economy, and provide better safety performance and driving experience. Automotive aluminum plates are usually made of high-strength aluminum alloys such as 5000 series, 6000 series and 7000 series.

Why is it that when the performance advantages of all-aluminum bodies are obviously superior, the proportion of all-aluminum bodies on the market today is only 1%? It's simple. Expensiveness is still the main reason. On the one hand, the smelting cost of pure aluminum and the processing cost of aluminum alloy are higher than steel, and the price of aluminum alloy itself is high; on the other hand, the processing technology is relatively complicated.

Doors and hoods are covers that have very low strength requirements, and the most important requirement is the rigidity and deformation. Ordinary mild steel or 6 series aluminum plates can be used here. The weight reduction effect of aluminum plates is very obvious in these parts.

ASTM6061has great advantages in making automobile body sheet parts. Body sheet parts affect the manufacturing of the entire body to some extent, so the material selection is also very important.

6061 aluminum sheet is currently used more for automobile fenders. 6061 aluminum sheet has good mechanical properties. Its density is only 1/3 of that of steel, and its machinability is 4.5 times that of iron. 6061 aluminum alloy automobile fenders neither increase the weight of the vehicle nor damage the car. The oxide film formed on the surface of 6061 aluminum sheet can prevent the fender from rusting.

AA5754 car aluminum sheet has an excellent strength-to-weight ratio. It has good corrosion resistance and is particularly suitable for automotive manufacturing. It is often used in a variety of parts, especially automotive covers and fuel tanks. Haomei Aluminum has the main 5000 and 6000 series aluminum alloys. Welcome to inquire what you need from us.
