Aluminium 3003
3003 is a manganese-bearing wrought aluminium alloy.
Identity / state reference
What distinguishes this material
Annealed O and strain-hardened H14 tube/pipe have distinct rows; a percentage strength comparison with 1100 has no shared state basis.
- Designation in this reference
- 3003
- Forms covered by the sources

- Temperature and exposure
- No general service-temperature limit or temperature-independent strength is established by this page. Check the temperature and duration for the specific source table and application.
Property evidence for a stated condition
No condition-specific numerical table is reproduced here
The linked sources establish the identity and the stated product/state scope. Obtain the row for your actual form, section, treatment and test conditions before adopting strength, hardness or a thermal limit.
Resolve these conditions next
- Does the order specify O or H14 and a tube/pipe product standard?
- Obtain the full material certificate, governing specification/edition, product dimensions and test direction before adopting a property value.
For machining, take the exact grade, supplied condition and measured hardness where applicable into the tool maker’s application data. A generic material-family speed is not a substitute for an operation and tool-specific recommendation.
Sources and what they establish

Kaiser Aluminum — 3003 Tube and Pipe ↗Source identity, a named product example and a supplied-batch certificate are different evidence. Cross-standard similarity does not approve substitution.
Corrections from the previous article
- Remove '20% stronger than 1100' and unqualified 130 MPa; do not treat one machining range as all conditions.
- Remove the untraceable generic machining recommendation (250 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
Compare a different sheet-alloy family
Read the 5052 identity and temper separately when comparing sheet materials; a shared product form does not imply equivalent properties.
