These sheets are tempered to a 1/2-hard or full-hard state to make them over twice as strong as standard 1100 aluminum.

The textured surface on these sheets increases rigidity and hides fingerprints and dents.

3003 aluminum stands up to outdoor use, as well as exposure to chemicals. It offers a good combination of strength, formability, and weldability. It's often used for storage tanks, heat exchangers, and general sheet metal work.
