7075 aluminum tube
I’ve looked everywhere to buy a piece of this material,does anyone know where to get this material in small quantity .thanks

yes- but that’s why you have a Ti reservoir made!! 😆
The weight of a steel tube is the draw back to the otherwise fantastic HW-100 guns. It just makes them so darned heavy. Fantastic guns though!
I think that cause the strength of TI u can get away with a thinner material and still be stronger than aluminum. thus being close to the same weight as aluminum.
Ah. And there it is. I guess an equivalent sized steel reservoir would weigh a lot. 19″ long by 1.5″ O.D. in steel would be pretty heavy. Not be 400cc’s and be able to hold 3400 psi… :biggrinn:
Ti was developed to be as strong as steel, at less weight, and anti corrosive. It is pretty much exactly between alu. and Steel in weight. Ti. is apx. 1/2 the weight of steel by volume. And Alu. i 1/2 of that. It is stronger than alu., and therefore, can be used in much thinner sections. There by making a ti. tube that much lighter than it would have been. The real advantgage is the strength. Not the weight savings. There probably won’t be any. Unless replaceing steel. 😉

Heavier than Aluminium? I thought the point of using Ti was to drop weight, and be able to run a bit higher pressure in the reservoir?
Yep, Ti is some great stuff. Heavier than Alu. and much harder to work. But tough as nails. Well, much tougher than nails I should say. 😆

If I knew you wanted to make a reservoir I would have told you that in the second post! To is totally a better material!! I have one!
I stand corrected. They do make it but it seems as rare as hell! On another note. 7075-t6 is very brittle. I don’t know if it would make that great a resevoir material. Titanium tubing like 3Al-2.5V would make a better candidate imho.
Hell, it’s NASA, if they don’t have it, they’ll make it!! :rofl:
some one has to be doing it. Wish I still had my connections at NASA In Huntsville ALA. If their contractors don’t have it, they can get it!
No argument there Knife, but I’m sure he’s looking for 7075 big enough for a frame…
They dont? Hummm, that’s strange. Easton has been making their arrow shafts from 7075 alu. tube with a T-6 heat treat for YEARS! 😉
yeah, I did a search for this too… 7075 round bar, onlinemetals.com…

Nope, for no more pressure than the hw can use, Ti would be way too expensive and unnessicary. Still heavier than what an alu. tube would need to be for the pressure level.
Not only i sTi MUCH more expensive, but the cost of machining is a LOT higher. And not just anywhere can do it. To make the Ti tube thin enought to not be heavier than the Alu, it would be so thin that the threading would be critical. It”s just not a good choice for a thiner tube ment for lower pressures. If you were wanting to go 4000+, then yes, It would have it’s place. But way over kill for standard air tanks.
Don’t get me wrong. If you have deep enough pockets to waste money, why not. Why not have a 500.oo dollar tube when you could of had a 100.00 tube. I mean, it’s only money! 😉
