Aluminum
Aluminium 5086
5086 is a separate wrought Al-Mg alloy, not an alternate spelling of 5083.
Identity / state reference
What distinguishes this material
Chemistry identity does not prove that 5086 stock can replace 5083 in a welded or marine specification.
- Designation in this reference
- 5086
- Forms covered by the sources
- Rolled product
- States to distinguish or confirm
- Obtain the full temper suffix from the certificate
- 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
- Which 5086 temper and product standard are on the certificate, and is substitution explicitly approved?
- 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.

Kaiser Aluminum — Chemical Composition Limits
Wrought alloy composition identities including 3004, 5083 and 5086; not product-state strength or substitution approval.
Kaiser Aluminum — Chemical Composition Limits ↗Laminati Alluminio Gallarate — mechanical characteristics
Manufacturer rolled-product table labelled UNI EN 485-2:2013; includes 5083 and 5086; identity/form only used here, not a complete current standard.
Laminati Alluminio Gallarate — mechanical characteristics ↗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 the universal strength/formability ranking against 5083 and unconditioned 275 MPa/70 HB.
- Remove the untraceable generic machining recommendation (210 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
