Aluminum
Aluminium 7050
7050 is a separate high-strength wrought aluminium grade.
Identity / state reference
What distinguishes this material
A thick-section application does not justify replacing a specified 7075 part or collapsing all 7050 tempers into T7451.
- Designation in this reference
- 7050
- Forms covered by the sources
- Sheet
- Coil
- Plate
- States to distinguish or confirm
- Full temper and thickness qualification must be confirmed
- 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
- What exact temper, section thickness, orientation and toughness/corrosion requirements are specified?
- 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
Reviewed 23 October 2026. A source’s publication date and the review date are different. The scope below identifies the fields checked.
Kaiser Aluminum — 7050 Sheet Coil and Plate
Sheet, coil and plate identity; detailed temper/section qualification must follow procurement data.
Kaiser Aluminum — 7050 Sheet Coil and Plate ↗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 universal 510 MPa/150 HB and the absolute claim that 7075 loses strength deep in every part.
- Remove the untraceable generic machining recommendation (140 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
