only true for high magnesium Ti alloys, and only when it is coming in contact with steel.
No, Titanium oxides very quickly when heated, as such it's always casted and heated in vacuum
Titanium by itself, pure titanium, can start a metal fire if heated enough. Fair, it doesn't last long, cause the reaction isn't self sustainable, but it is more than enough to melt a bit and ruin your barrel.
For single shot precision weapons, maybe, but for anything else you are begging for a deformation in your barrel and thus either misfires or backfires.
We do. There are companies making titanium barrels. It isn't used in very high pressure ammo yet, but for example various shotgun barrels are made from titanium now as well as many rifle actions even for very hot magnum rounds. titanium is just hard to work with.
Titanium is a total homosexual to work with, because of the very properties you listed. Idk what youd have to use to cut the rifling, probably some ceramic shit.
yeah can't really cold hammer forge titanium unfortunately, otherwise that would have been perfect when cutting it is so annoying.
you can but you need a lot more force per impact, and need to work in a really cold environment. it has been done on a small scale.
you can etch titanium with some forms of marker
see NOW I'm curious if we can get titanium tubes that can withstand high pressure and ECM rifle it.
Titanium is a bitch to purify. Also a pain to shape into a desired shape.
because it's ass to machine and costs more
very few people care about saving mass when they can save 100 buckaroos instead
Hi, anon. You are in luck me and my manufacturer are in the process of making and testing Ti Barrels for a certain Bullpup that's going to be released. It's also going to be the first USSOCOM adopted bullpup in history so my crew and the undisclosed bullpup mfg will go into the annals of history of American Bullpup Superiority
While I assume you're a liar I hope you aren't, though
>It's also going to be the first USSOCOM adopted bullpup in history
doesn't sound good, military hasn't historically cared about rifle accuracy outside of designated marksman or snipers. But I guess it'd be cool anyway.
Difficult to keep sharp, same reason they don't make knives out of it. Rifling needs to stay unwarped/sharp.
>Look at me Im a kid who saw on the internet that titanium is hard so everything should be titanium.
Come back when your balls drop.
Like others said, Titanium is a bitch to work with. Life isn't anime.
>Titanium is a bitch to work with.
Yeah, for the very same reasons that make it a very good material for a variety of machinery.
>Life isn't anime.
>He hasn't found the olive green ticket
I feel sorry for you
is anyone doing powder sintering for barrels?
>sintering a barrel
Please do not do this.
>sintering Titanium
Possible, but very difficult to remain in chemistry spec if you aren't one of the handful of places that has figured it out.
porous as fuck
They should make them from diamond, the strongest metal known to man
Ti can't be made as hard as steel and although it has more tensile strength it isn't as rigid.
China has the majority of the world's titanium and most Ti consumer products are made with Chinese material. This is not good for security.
Futuristic barrels will probably be made of ceramic composite
Bruh it's softer, it will wear out rapidly compared to a high alloy steel like 4150
>Why aren't we using titanium barrels yet?
Multiple reasons, but basically first reason is Steal is way more versatile. You control the quantity Carbon in the steal to change its proprties.
And we can make steel alloys.
Like a famous example is Vanadium Steal, it's the invention that was implemented in the Ford Model T and made it a huge sucess.
Second reason is the hardness of Titanium makes it very difficult to machine, and as a material gains in hardness, it usually becomes more brittle.
Like with Knives for example.
Titanium is harder than steel but it doesn't mak for good Knfe blades, as it loses its edge way faster than steel.
>Like a famous example is Vanadium Steal, it's the invention that was implemented in the Ford Model T and made it a huge sucess.
Vanadium steel wasnt fords invention, he stole that off some frenchie IIRC.
>stole that off some frenchie
Vanadium is clearly a lituanian name anon
Because it's expensive and hard to work with while steel does the job just fine.
>steel does the job just fine
crazy how often this applies
it's because of just how many alloys we've been able to create with iron and carbon and little additives here and there. It's absolutely nuts how advanced our alloy chemistry as well as manufacturing has become. Add all sorts of heat treating and stress relieving techniques and spectra, and you can essentially find a steel for nearly every application that does the job just fine and adequately.
1) Low brinell number, much softer than quality steel alloys
2) Less elastic, that's one of the reasony why it's harder to machine
3) Purifying is super complicated
4) Doesn't handle high temperatures as well as steel (inb4 jet fuel)
5) Bitch to weld
There are fields where Titanium (or to be correct: Titanium alloys) shine. But it sure ain't no "trumps steel in every aspect" metal. I'd want high quality steel gun parts every day over some titanium gimmick.
And I write this as someone who wears a wedding band made from titanium because he didn't want pussy soft-ass metals like gold or silver
wait so am I extra retarded for slurging on a titanium bcg? I did no prior research btw just went boomer with "TITANIUM STRONG"
>wait so am I extra retarded for slurging on a titanium bcg?
I'm sorry but yes you are. You would have done better if you had bought a high quality (defense-) alloy aluminum one.
As I said: Titanium alloys got their niches where they shit on everything else. But those are rather small. For most gun related stuff high-quality steel and aluminum alloys are the better choice, even if they're only cheaper.
Just like virtually nothing is made from pure aluminum or iron nothing is made from pure titanium.
Most metals we use are alloys, even if they are rahter basic likr carbon steel which is iron and (less than, but not much less than) 2.1% carbon
anon lots of things are made from pure metals.
and a Ti-64 alloy could be useful for barrels but it's stupid expensive.
You’ll probably want to use a heavier buffer to make up for the lighter BCG. The carrier isn’t a common failure point, but it is part of the reciprocating mass that keeps your rifle running at an optimal rate. Too little mass and you can a) outrun the magazine spring or b) try to extract the case too early and end up tearing the base off of the case, meaning rifle don’t go bang. that’s a rather extreme case, and I don’t think the ounce in weight difference is going to do it on an otherwise well made gun, but if the barrel is as wide as Mia Khalifa, that’s only going to make things worse
You could also do an adjustable gas block and eyeball the ejection pattern. A lot of competition guns are or used to be setup this way. The problem then becomes that in adverse conditions, the reciprocating mass from a light buffer, titanium carrier, and just enough gas to keep things at 3 o’clock when clean and lubed, may not have enough momentum to push through debris. But again, this is worst case.
You’re presumably a grown man and can decide for yourself whether to keep your titanium BCG now that you know some of the potential downsides
Right, I mean we can dream of some single crystal super alloy barrel and sure it'd be rad but nobody wants to spend $100k per barrel lol. And it's not an unvarnished win in everything regardless, there's also complexities around how it handles wear and use. Still useful in some circumstances.
>I'd want high quality steel gun parts every day over some titanium gimmick.
It works well in suppressors that aren't intended for full auto, in principle it'd probably work great even in full auto for pistol calibers since those are so much lower pressure and volume. But at any rate it can be a good tradeoff, at the range whatever but I'm glad to have a decent ti can and one more on the way for hunting and woods gun.
Is the first time you hear about titanium? Steel is far stronger and far cheaper. Titanium is a retarded material in most aplications, except when weight is a deciding factor, like in planes.
>softer than 4140 and 4150.
yeah.
Titanium doesnt have good friction properties. You would probably want to chrome the chamber and bore. Aside from that, only the cost and nightmare of trying to gun drill the stuff. it eats tooling. You would easily exceed Proof carbon barrel costs to build a 6al4v barrel
There was a company back in 2012 i think that was turning steel barrels down to liners and building them back up with spray welded titanium. I don't know if they are still around though
Titanium barrel for a custom built sniper rifle would be kino, but I can't see it being used for mass production, shit too hard and expensive.
>world's titanium supply is in Russia
>currently letting a second rate military kick their ass while we sanction them
Hmm. Also, steel is super cheap in comparison. OP is a fag.
Japan and Florida have titanium mines too, numbnuts
A handful of lightweight revolvers have titanium cylinders and they get absolutely rekt if you shoot the wrong load through them. A single cylinder of lightweight, high velocity .357 is enough to cause significant damage.
The largest workable titanium deposits on earth are roughly under the Ukranian war right now.
Theres a reason why cast titanium parts that look like an iron skillet is still relevant. Titanium is a bitch to cold hammer forge.
Doesn't titanium have limited load cycles?
It's more brittle than steel so I can picture it cracking more easily.
I can tell there isn't any machinists on this post. Ti is difficult to machine because its sticky and
gummy, not because of its hardness.
To machine Titanium you need the absolute highest pressure coolant flow and volume to clear chips.
Titanium is a horseshit material for a gun barrel. It will erode and not hold up at all. Titanium is a poor choice for any interacting moving parts.
Titanium is literally only good for corrosion resistance frames and structural material. Air frames, sub frames, bike frames, even stainless steel maybe a better choice for bone screws.
