What are the advantages and disadvantages of using aluminum sheets for car body panels?

Aluminum sheets offer several advantages for car body panels, such as reduced weight, which can improve fuel efficiency and handling. They also have high resistance to corrosion, enhancing the vehicle's durability. Additionally, aluminum is easier to recycle, contributing to environmental sustainability. However, there are downsides, including higher cost compared to steel, which can affect the vehicle's price. Aluminum is also less malleable, making it more challenging to repair after accidents, potentially leading to higher repair costs. Furthermore, aluminum's lower strength compared to steel can necessitate thicker panels to achieve the same structural integrity, which may offset some of the weight savings.
