Aluminium Alloy 3003 is a non-heat-treatable aluminium-manganese alloy known for good formability, corrosion resistance and moderate strength.
Suitable for bending, deep drawing and general forming in appropriate tempers.
Provides good general atmospheric and service-environment corrosion resistance.
Offers higher strength than commercially pure aluminium while retaining useful ductility.
Strength is mainly controlled through cold work and temper.
Aluminium Alloy 3003 is selected for applications that match its specific strength, corrosion, forming, machining and service characteristics.
Commonly used for tubing, fins and formed heat-transfer components.
Suitable for fabricated household and food-service products.
Used for sheet, formed parts and panels.
Selected for applications requiring good formability and corrosion resistance.
Choose temper based on forming requirement versus strength requirement.
Good forming behavior makes 3003 suitable for complex sheet-metal shapes.
For heavily loaded structures, a stronger heat-treatable or 5xxx/6xxx alloy may be more appropriate.
The commonly listed Werkstoff / EN cross-reference for Aluminium Alloy 3003 is 3.0517. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
No. Strength is increased mainly through cold working.
Yes. It generally provides good corrosion resistance.
Typical uses include heat exchangers, cookware, sheet-metal products, panels and general fabrication.
