inaccuracy and needed background
The aerospace section lists titanium as a component used in the compressor blades of various currently produced high end commercial aircraft turbines. This is false. Its widely known and easily verified that these types of jets and turbofans use *Rhenealloys* and their composition is one of the factors that subjects these components to export restriction or other controls. the 2nd point is just an addition: The segment about the A12 and SR71 and the latter discussion about the Soviet Union's submarines is missing a highly informative tidbit: The US government purchased the titanium for the SR71 FROM the soviet union, at the time by far the only source of the metal in sufficient quantities for the fleet of aircraft. This information can be found in the autobiography of Kelly Johnson of Lockeed Martin Skunkworks. I can't remember the specifics offhand, but IIRC they were purchased by CIA intermediate front companies. Obviously, the soviet union has been known to do that sort of thing over the years (eg they used to be the global 1st source for solid rocket motors for space launch platforms, which would of course include launches of spy satellites and whatnot)67.165.123.62 (talk) 08:11, 14 February 2023 (UTC)
Notify the readers that we are reading the article about chemical element.
Information is included above as you can see. 2001:EE0:4BC4:5DC0:74A5:B633:51B2:265D (talk) 11:58, 26 November 2023 (UTC)
- We are reading about it because it says Titanium (disambiguation) 2603:8080:D03:89D4:74C6:A02F:A110:E938 (talk) 03:36, 25 August 2024 (UTC)
- It is not clear what you are asking. Polyamorph (talk) 12:01, 25 August 2024 (UTC)
Refractory metal
Is titanium included in the widest definition of refractory metals? 174.103.211.175 (talk) 15:33, 16 January 2025 (UTC)
- Yes, in the widest definition, but not in narrower ones. "Refractory" is often regarded as a melting point about 2000°C and Ti is a bit below this, but above steels. Andy Dingley (talk) 15:38, 16 January 2025 (UTC)

Large amounts of text are just copy and pasted from https://www.trysigma.com/cnc-machining/titanium-alloy-parts-processing-factory.html. Before renominating, this issue needs to be addressed
Hi @PeriodicEditor: I am completely certain that this article is a victim of WP:BACKWARDSCOPY - that is, that the website(s) that contain large portions of this article have copied it from us and did not provide attribution. I believe this because the component parts of the copied text largely existed from the point when the article was promoted to "featured article" in 2007: note primary fabrication, whereby an ingot is converted into general mill products such as billet, bar, plate, sheet, strip and tube. The Trysigma page was likely copied over some time after 2018 when our article came into a form similar to the current one. -- Reconrabbit 20:16, 12 November 2025 (UTC)
- See also https://pse-info.de/en/element/Ti which copies Wikipedia and gives the wrong creative commons license and https://www.xuboti.com/material-titanium-alloy/ which copies some paragraphs for its Q&A, including the very first one. If you want to close this review: try using User:Novem Linguae/Scripts/GANReviewTool. -- Reconrabbit 20:23, 12 November 2025 (UTC)
- Thank you for letting me know, I will re-review it, I thought it had copyvio so instant failed it. PeriodicEditor (talk) 04:51, 13 November 2025 (UTC)
GA Criteria review
1. Well written -
2. Verifiable - Well sourced and no evident original research. No copying other than ones caused by WP:BACKWARDSCOPY
3. Broad in its coverage - Covers all major properties and uses for titanium
4.Neutrality - No bias
5.Stable - No edit warring
6.Illustrated - Well illustrated and has good captions. All media is public domain
All images are open licensed, bu not all are "public domain". Some are CC for example. DMacks (talk) 07:35, 13 November 2025 (UTC)
- Ok, I just got confused and this is my first GA review, so thanks for the feedback. Does it make a difference for the review, it being CC? PeriodicEditor (talk) 07:38, 13 November 2025 (UTC)
- It does not make a difference in this sort of situation. WP:GACR6 does not say anything about what licenses are/aren't allowed. DMacks (talk) 07:43, 13 November 2025 (UTC)
- Can you take a look at some of the sources and confirm that they support the text? This is a requirement in step 3 of the GA instructions. -- Reconrabbit 14:54, 13 November 2025 (UTC)
- I have, did you find any that didn’t PeriodicEditor (talk) 17:01, 13 November 2025 (UTC)
- You can note which parts you checked. See for example Talk:Radium/GA4 under "Sources spot check". -- Reconrabbit 17:06, 13 November 2025 (UTC)
- I did check sources, I just didn't note it down. Thanks for telling me PeriodicEditor (talk) 17:08, 13 November 2025 (UTC)

Incorrect percentage for India in table "2024 production of ilmenite and rutile"
India produces 222 thousand tonnes of ilmenite and rutile, which is 2.4% of the world total of 9360 tonnes. (Currently, the table wrongly states 4.3%.) Ondřej Holešovský (talk) 14:09, 4 February 2026 (UTC)
- I do not know how I made that mistake, thank you, it is fixed. -- Reconrabbit 15:47, 4 February 2026 (UTC)
