The term "aluminum body" refers to a type of automobile or vehicle construction where the primary structural components, such as the frame and panels, are made from aluminum. Aluminum is a lightweight metal that offers several advantages over traditional steel bodies in terms of weight reduction, corrosion resistance, and improved fuel efficiency. An aluminum body can also provide enhanced safety features due to its high strength-to-weight ratio. Overall, the use of an aluminum body results in a lighter, more durable, and environmentally friendly vehicle design.
