What is the difference between aluminum plate and aluminum sheet？

The main difference between aluminum plate and aluminum sheet lies in their thickness. Aluminum plate typically refers to thicker pieces of aluminum with thicknesses starting from around 6 mm (0.25 inches) and above. These plates are usually used in structural applications where higher strength and durability are required.

On the other hand, aluminum sheet usually refers to thinner pieces of aluminum with thicknesses ranging from about 0.2 mm (0.008 inches) to 6 mm (0.25 inches). Sheets are often used in applications where lightweight and flexibility are important, such as roofing, cladding, and decorative purposes.

In summary, the primary distinction between aluminum plate and aluminum sheet is their thickness, with plates being thicker and sheets being thinner. Additionally, aluminum plates are typically used in structural applications, while aluminum sheets are used in a variety of applications requiring lightweight and flexible material.
