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)[reply]

Information is included above as you can see. 2001:EE0:4BC4:5DC0:74A5:B633:51B2:265D (talk) 11:58, 26 November 2023 (UTC)[reply]

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)[reply]

It is not clear what you are asking. Polyamorph (talk) 12:01, 25 August 2024 (UTC)[reply]

Is titanium included in the widest definition of refractory metals? 174.103.211.175 (talk) 15:33, 16 January 2025 (UTC)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

I have, did you find any that didn’t PeriodicEditor (talk) 17:01, 13 November 2025 (UTC)[reply]

You can note which parts you checked. See for example Talk:Radium/GA4 under "Sources spot check". -- Reconrabbit 17:06, 13 November 2025 (UTC)[reply]

I did check sources, I just didn't note it down. Thanks for telling me PeriodicEditor (talk) 17:08, 13 November 2025 (UTC)[reply]

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)[reply]

I do not know how I made that mistake, thank you, it is fixed. -- Reconrabbit 15:47, 4 February 2026 (UTC)[reply]
