3003 is a wrought aluminum manganese alloy widely supplied as sheet, coil and plate. It provides moderate strength with good corrosion resistance, weldability and forming ability. Strength is developed by cold working rather than precipitation heat treatment. Annealed material supports drawing and spinning, while H14 and H24 offer greater handling strength. Typical uses include fabricated sheet components, heat exchangers and building products. Selection is usually driven by ease of fabrication and corrosion performance rather than high structural loading.
