Aluminum 3003
Aluminum 3003 is a widely used Al-Mn alloy combining good formability, moderate strength and corrosion resistance.
Alloy basis
It is non-heat-treatable and strengthened by cold work.
Typical applications
Heat exchangers, HVAC fins, roofing, cookware, tanks, signage and general sheet-metal work.
Common tempers / conditions
Common tempers include O, H14, H16 and H18.
Engineering selection notes
Confirm the exact alloy designation, temper, product form, thickness/diameter, mechanical properties, corrosion environment, joining process, surface treatment and certification. Properties can vary substantially by temper and product form.
QA/QC
For critical service, verify heat/lot traceability, mill certificate, chemical composition, tensile properties, temper, dimensional tolerances and any required NDT or third-party inspection.
Element Folio engineering reference. Verify the latest governing standard and producer data before design or procurement.
