3003 h14 aluminum sheet

3003 H14 aluminum sheet is a non-heat-treatable Al-Mn alloy aluminum sheet with medium strength, excellent corrosion resistance and good formability. The H14 temper means the sheet is strain-hardened to a half-hard condition, making it stronger than annealed 3003-O while still maintaining good workability.
