Which of the following is an advantage of aluminum over steel?

Choosing better corrosion resistance as an advantage of aluminum over steel is accurate. Aluminum naturally generates a protective oxide layer when exposed to the atmosphere, which helps prevent further corrosion from environmental factors. This inherent property makes aluminum particularly suited for automotive applications, as vehicles are constantly subjected to moisture, salt, and other corrosive elements.

On the other hand, steel tends to rust when exposed to moisture without proper protective coatings. The need for additional treatments, such as painting or galvanization, increases the long-term maintenance considerations for steel components. Therefore, aluminum’s superior corrosion resistance not only enhances the longevity of parts but also contributes to reduced maintenance requirements, making it a preferred choice in many modern vehicle designs.
