Yeah makes sense, I was wondering if it had to do with Tungsten’s harness/MP
Yup… a tungsten billet has to be heated to point where it begins vaporize (this is considered the MP, but I’ve only ever seen it vaporize. And by seen, I don’t mean look at, it’s bright like the sun) At these temperatures it also becomes a brittle ceramic and is prone to cracking. Lots of scrap to get one good piece that can then be machined to net form.
