3003 aluminum sheet belongs to the 3000 series aluminum-manganese alloys, with manganese as the primary alloying element. Compared with 1000 series pure aluminum, 3003 offers higher strength while maintaining good formability and corrosion resistance, making it one of the most widely used aluminum alloys for general-purpose applications.
