Titanium
Ti-3Al-2.5V
Ti-3Al-2.5V is identified as ASTM Grade 9 / TIMETAL 3-2.5 in the producer source.
Identity / state reference
What distinguishes this material
TIMET describes it as alpha/beta; the palladium-bearing Grade 18 variant is separate.

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
- Is the product Grade 9 or the Pd variant, and is it annealed or cold-worked/stress-relieved?
- 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-3-2.5
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-3-2.5 ↗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
- Correct the old near-alpha classification and unsupported '25% stronger' and universal better-machining comparisons.
- Remove the untraceable generic machining recommendation (32 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
- The old O maximum 0.12% differs from the reviewed TIMET Grade 9 table 0.15%; do not publish the old composition as a governing acceptance table.
Distinguish titanium grades
Compare the grade, alloy composition and supplied form separately. A titanium family label does not establish the same strength or temperature scope.
