Selection summary
Overview
3003 is a registered wrought aluminum alloy commonly supplied as sheet and coil. Alloy number alone is incomplete buying information: temper, product specification, thickness, width, tolerances, surface, fabrication route, tests and certificate must be stated. Property and forming response vary with temper and product form.
This page separates standard-oriented limits from typical reference data. Purchase acceptance comes from the ordered specification and certified material test report.
Names and systems
Identity & standards
Similar designations across ASTM, EN, JIS, and other systems are not automatically interchangeable. Product form and ordered standard control chemistry, properties, dimensions, condition, and testing.
Reference chemistry
Composition
| Element | Reference range | Why it matters |
|---|---|---|
| Alloy or steel composition | Controlled by the governing designation and ordered edition | Supports identification and grade-level acceptance |
| Residual or alloying elements | Verify from the applicable standard and certificate | Controls processing and service response |
Concise grade-family reference only. Confirm every element limit against the current standard for the exact product ordered.
Condition matters
Reference properties
A designation is meaningful only with its governing standard, edition and product form.
Typical web values are screening information, not purchase acceptance limits.
Environment first
Corrosion behavior
Corrosion control depends on the complete material system and service environment.
Review coatings, lining, corrosion allowance or alloy upgrading where the medium requires them.
Temperature, concentration, deposits, crevices, stress, surface finish, cleaning, and fabrication quality can change service performance.
Service limits
Temperature & service
Confirm temperature limits through the governing design code, product standard and complete material system.
Delivery condition
Heat treatment & condition
Do not infer heat treatment or temper from an incomplete designation.
State the ordered condition or temper and verify it on the certificate.
Process route
Fabrication
Qualify forming, welding, joining and surface-repair procedures for the ordered product form.
Preserve material or coating traceability after cutting and secondary processing.
Magnetic response: Non-ferromagnetic.
Decision boundaries
Comparisons & substitution
5052 generally offers a different strength and corrosion-performance balance; compare the exact temper and form.
3003 and 5052 are not substitutes on alloy number alone.

Sheet, plate and coil in explicitly ordered tempers and applicable product specifications
Decision support
Selection guidance
Choose this grade when
- Moderate strength and forming are required and the selected 3003 temper is validated.
- The governing product specification and surface/finish requirements are known.
Review another grade when
- Higher strength, marine exposure, structural fatigue or pressure duty controls selection.
- The drawing omits temper, tolerances or product specification.
Before ordering
Procurement checklist
State AA 3003 and the complete temper designation.
State ASTM B209 or the governing product specification and edition.
State thickness, width, length/coil geometry, tolerances, surface, edge and quantity.
State forming/joining needs, inspection document, traceability, protective film and dry packing.
