Titanium
Ti-6Al-4V
Ti-6Al-4V is identified as ASTM Grade 5 by TIMET.
Identity / state reference
What distinguishes this material
Its microstructure and properties depend on thermo-mechanical history; Grade 23 ELI is separate.
- Designation in this reference

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 product form, section and thermal history are certified, and is the requirement actually Grade 5?
- 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.
TIMET — timetal-6-4
Producer datasheet for the named alloy; forms, heat treatments, typical/minimum labels and temperatures must be read per table. Legacy publication remains a reference, not a current procurement certificate.
TIMET — timetal-6-4 ↗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 950 MPa and the '45% lighter at comparable strength' shortcut without a matching design basis.
- Remove the untraceable generic machining recommendation (22 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
Check the ELI designation
Compare the ELI identity and its stated source scope with the base alloy record; retain the full designation on the certificate.
