What is the difference between aluminum sheets with different thicknesses?

Aluminum sheets with different thicknesses primarily differ in their strength, weight, and applications. Thicker sheets offer greater strength and rigidity, making them suitable for structural applications or heavy-duty uses. In contrast, thinner sheets are lighter and more flexible, ideal for applications requiring formability or where weight is a concern, such as in the automotive or aerospace industries. The choice of thickness depends on the specific requirements of the project, including load-bearing needs, durability, and aesthetic considerations.
