Aluminum sheet 2A12 alloy is the Chinese implementation of the GB/T 3191-2010 standard after replacing the GB/T 3191-1998 standard, corresponding to the United States 2124, and Japan 2024. The chemical composition of 2A12 aluminum sheet alloy mainly includes aluminum, silicon, copper, magnesium, zinc, manganese, titanium, and nickel. 2A12 aluminum sheet plate is a typical high-strength deformed aluminum alloy with good heat resistance and can be strengthened by heat treatment. Due to its excellent mechanical properties including tensile strength, yield point, and elongation, many countries like to use this alloy. Therefore, the 2A12 aluminum sheet is the most used aluminum alloy in hard aluminum.
