I’ve checked Francisl’s Link to Plansee a bit.
Plansee has Tungsten 1% Lanthanium oxide rods with a diameter of 8cm (3″) in stock (article number 268387), and pure 8cm diameter Tungsten rods (article number 148837), but those were not available yesterday.
On the other hand, they only seem to deliver rods at least 50cm long.
The corrected Plansee-Express link is here: https://www.plansee-express.com/
