What is the most common aluminium sheet grade?

The most common aluminum sheet grade used in various industries is 3003. It is a general-purpose aluminum alloy with excellent corrosion resistance, good formability, and moderate strength. The alloy consists primarily of aluminum, with small amounts of other elements such as manganese and copper.

3003 aluminum sheet is widely utilized in applications where moderate strength and high corrosion resistance are required. It is commonly used for building facades, roofing, kitchenware, heat exchangers, and chemical equipment. Additionally, its formability makes it suitable for intricate shapes and deep drawing processes.
