3004 aluminum sheet belongs to the 3000 series aluminum-manganese alloys, alloyed with both manganese and magnesium. Compared with 3003 aluminum, 3004 provides higher strength while maintaining good formability and corrosion resistance, making it a preferred material for applications requiring improved mechanical performance.
