Features: Aluminum alloy with manganese as the main alloying element, excellent corrosion resistance, weldability, and likeability, good anode film properties, and excellent wax solderability. It belongs to non-heat treatment. Disadvantages: low strength, but can be strengthened by cold work hardening.
Applications: Building panels (ceiling panels), panels, rain shelters, and various pressure vessels and pipes for sheet metal processing.

3003: Compared with 1100, the strength is slightly higher, and the extrusion processability and corrosion resistance are good. Heat exchanger materials, materials for general mechanical parts, etc.
