FAQ
What is 3003 H14 material?
3003 H14 is an aluminum-manganese alloy with strain-hardened temper, offering moderate strength and excellent corrosion resistance.
What does H14 mean in aluminum?
H14 indicates strain-hardened temper to half-hard, meaning the material is moderately hardened by cold working without heat treatment.
What is 3003 alloy used for?
Common applications include roofing, siding, tanks, ducts, decorative panels, and kitchen utensils.
What is the difference between 3003 0 and 3003 H14?
- 3003-O: Annealed, soft, excellent formability, lower strength
- 3003-H14: Strain-hardened to half-hard, moderate strength, still good formability
How thick is 3003-H14 aluminum sheet?
It is available from 0.3 mm to 6 mm, depending on type (sheet, coil, tread plate) and application.
