Aluminum sheets are not necessarily more expensive than other types of sheet metal. The cost can vary based on factors such as the current market price of the metal, the thickness and grade of the sheet, and the specific alloy used. Generally, aluminum is less expensive than metals like stainless steel or copper, but it can be more expensive than common metals like steel or iron. Prices fluctuate, so it's best to check current market prices for the most accurate comparison.
