Save your beans and buy some 7075 round bar and have it wire edm'd. Sadly, 7075 tubing isn't out there. I really wish onlinemetals.com offered more cutting services like that. Or maybe not, there would be more form 1's needing to be approved and slow mine down.
You know Wire EDM needs a hole to start with right? Sink EDM is a way to get that hole, so is gun-drilling. If it's short enough you can just turn a hole, but if you can do that you might as well turn the whole thing to the ID and skip the expensive processes. Not sure what you're thinking, but unless you want a $500+ 7075 tube, edm is absolutely the wrong tool.
7075 tubing is surely out there but unless you're going to buy 100kg or $20,000 of it (which ever costs more) it might as well not exist. 2024 is pretty good, and readily available.
Now, if someone can find 8000 series tubing with scandium, well, that would interesting! I've never been able to figure out what "scandium" bikes really are and it seems no one knows much on the matter. I suppose the Russians would be a place to start because it's like "their" titanium.
