Special project coming up and need to find some aluminum tubing. Google is not finding anything except for whole sale suppliers. I am sure they wont bother with my needed 2 feet unless they give out free samples.

I have searched Enco, SpeedyMetals, OnlineMetals, McMaster-Carr, and MSC no luck. Lots of 6061, but no 7075.

Needs to be: 1"OD x 0.087"ID (.065" wall thickness) aluminum 7075 tubing.

I will need 2' in either one length or two 1' sections....

I will be coming to the north Denver area at the end of January if anyone knows of any retailing metal shops....

Lowes menards Home depot all have aluminum racks with small length but not sure what grade it is. Other wise it will be One of the supply houses and a cut short order fee.

Do a search for aircraft tubing suppies. You should be able to find an aviation supplier to fill your needs. I worked for a corporate aviation repair station in Dallas for awhile after retiring from the USAF and they stocked virtually any size of tubing you could imagine. What you could find in the metal scrap bins was amazing.

I have a piece of 6061 that is 1 inch, and has a .022 wall thickness if that will do you any good. You can have it for nothing. Let me know. The toolman.

Still striking out...aircraft supply was a great idea, but no 7075 1" tubing. I found Dillsburg Aeroplane on facebook, but tried calling with no luck.
I have a plea into Mack Bros suppressors in nearby Sturgis, SD for some scrap...wish me luck.

Thanks for the offer JMtoolman, but that will be too thin for me. I may have to just settle for 6061 when I order everything else from onlinemetals .

Wicks and Aircraft Spruce are two of the biggest homebuilder aircraft suppliers and neither have 7075 tube. What is the reason for 7075 specifically in lieu of 6061 or 2024?

cheese1566
01-16-2014, 02:44 PM
Strength.
I am going to build a 22LR suppressor when my Form 1 tax stamp is approved and sent back from the ATF.
Most silencer manufacturers go with 7075. I have researched that 2024 is strong but has some corrosion disadvantages. 6061 may suffice, but you get one chance to build after approval.
I can always go stainless for the tube, but there is a 3 ounce addition to the weight of the suppressor.

My baffles will be 7075 as I can get round stock from online metals.

Will you be welding this? Good finishing (paint, anodized, etc) and frequent cleaning can prevent a lot of corrosion. Stainless steel and aluminum in contact with each other can and will give you galvanic corrosion. If you use 6061 you would likely want a thicker wall tube.

cheese1566
01-16-2014, 03:12 PM
No welding, just threading of the end caps. The mounting cap for the barrel will be stainless. I may anodize the baffles for fun, but the tube finish will be GunKote as I have the tooling and materials already. I can lightly spray the internal tube threads to inhibit corrosion, but wont be able to touch the middle of the inner tube. GunKote wont gunk up the threads as regular paint would.

But of course, I could always stainless and just wipe it down and never have to finish it.

2024 is the next best high strength option. The 45K ultimate tensile strength of 6061T6 should be more than adequate for 22LR.
I'm coming up with nothing for 1" 7075.

I went ahead and submitted a Q request, I'll let you know what they come back with. I've always had fine luck with the large houses supplying me with small order stuff, they know I'll be back for large orders and I remember who helps me out and give them the business. I have a machine shop, if the quote they come back with is good for you I can just have them drop ship it to you.

For a .22 you'd be fine with T6. Heck, I've used T3 for a 300 blackout build. As far as thickness goes, you're only limited by your threading - it has to be thick enough to thread. I've done a few silencer builds with aluminum, right now I'm gearing up (improving my tooling) to do a few silencer builds from titanium. I've got the material, Form1s in hand, but not all the tooling I need to do the job right.

Please keep us posted on how it goes.

Lots of 22 tubes are 6061 T6 and the baffles are 7075 for the reasons that you are already finding out.

Just go with the 6061 and be done with it. Its more than adequate.

That's what I am thinking... Getting too darn hard to find and 6061 should be satisfactory.
I do have a few more months of waiting for my stamp to accumulate.

Dumb question, but exactly why is there only one shot to build this? you have a SN and an approval, right? If it needs to be rebuilt, then with the door closed afterhours with a sold chunk of time to get what is important to get done, done... Followed by complete (complete) destruction of the old, who is to know? There is the letter of the law and the spirit of the law. And if we were to all judged on the letter of the law, we would all be criminals. Only the spirit of the law allows us to maintain critical thinking, morality, and ethics while remaining a law abiding citizen.

That is just my thought on the matter.

Well, ATF actually has conflicting letters on this. However, the prevailing "rules" are. . .

Your Form 1 is a license to make and register. It is not a license to tinker, fix, or rebuild. Only a Title II licensed manufacture may do those activities on an existing silencer. This is one of the results of the "Gemtax" controversy of 2011 (If I have the year right).

Thats how I understand it. Once the tube is made and serial numbered, thats it. Once the supressor is made thats it. I cannot fix it, modify, or replace parts since its a Form 1 build and I am not a licensed manufacturer.
This is why I am taking the time to consider worthy materials and think it through. I also have to weigh in other factors as cost, weight, life span of the suppressor (I am only 41 years old) and my own personal machining capabilities as well.
My form is only two months in to the ATF and I am sure I have numerous more in wait until approval (pretty confident). No need to rush into it.

I used 6061 for the one I built. Came from Wicks, where you can buy it by the foot. It's old and has never shown any signs of stress or damage.

cheese1566
01-18-2014, 10:31 AM
I received a quote from rancocasmetals.com in a timeley fashion.
They have it, but for $150+shipping per 12 foot section. The section is cut down to two 6' lengths for UPS delivery.

Without shipping, that comes to $12.50 per foot. So with shipping, we could probably safely say at least $14 a foot.
To large of an initial expense for me, unless I could find buyers to fullfill the other 10 feet. But then you come into trying to sell a 4' and a 6' length section and the additional added shipping on top of that, bumping it up to ~$20 per foot for shipping depending.
Online Metals has 6061 for $5.50 a foot...

I'm not sure your going to find 7075 in tubing, but you can get 2024 which is about 50% higher in strenght than 6061 I checked one of my old Jorgensen books and they don't even list it. Hope you are not going to do any welding on this material. Sprink

Cheese: Try Tube Sales or Tube Service in LA. They will both have what you want, and anything else you can think of as well. However expect to hear high prices as they specialize in the oddball sizes and materials.

You will run into the 12 foot minimum just about everywhere you go. No outfit is going top sell you a 1 or 2 foot piece of a specialized material unless it is a remnant, and if they won't sell less than a 12 foot section there won't be any remnants.

it would be a different story if it was 6061 which is far more common and they would be assured of selling the Rems as they appeared due to higher demand.

7075 is over kill for what you are doing anyway. 6061 would work just fine, and a lot cheaper to buy and more readily available.

Now if you were suppressing a .300 Win Mag then I could see the 7075, Anything below that and 6061 is more than adequate.

Thanks for all the help and experience guys!
I think I may settle for 6061 for the tube. I just get anal sometimes and get hung up.

I plan on using 6061 for the tube and 7075 rod for the baffles and end cap. And maybe stainless or tool steel for the initial blast cap and muzzle threaded end cap. I can get these easily from onlinemetals.

But I still have plenty of time to keep looking.

I can resist no longer. How about Titanium? There's an outfit out of California that buys scrap from aerospace companies and sells it for fractions of retail. I just bought 4 feet worth (in 1 foot sections) of 1.625 diameter Grade five round stock from him for my upcoming projects.

This is what I sent in a PMed requist for contact info:


This is them: http://www.sackinmetals.com/materials.htm

If you want to see what the have available they list that on their Ebay store. http://stores.ebay.com/Sackin-Metals-Inc?_trksid=p2047675.l2563 Do NOT buy through their Ebay account though. Call and dicker with them a bit. On a good day you can get a better deal.

Don't know if your familar with Titanium or not. I'm very green with it myself and have yet to cut a curl of it. I've got my materials but not all my tooling. I'm upgrading my old Atlas to better cut the Titanium. Grade 5 Ti does not come in tubes. It cannot be drawn. If you want the tube Grade 5 you have to start with bar and bore it out. AAC was doing that but military demand got so great they switched to Grade 9 tubing w/ Grade 5 internals. That's what I'm planning on doing. Sakin did not have the tubing I needed so I bought that (full retail) from Titanium Joe in Canada. His card is out in the shop If you need his WWW I can get it tomorrow.

Any Cal.

Curious, can you use a high temp antisieze on the threads to prevent the stainless from reacting to the aluminum? I don't think the temp is going to be much hotter than a 17K RPM high compression motorcycle engine with aluminum heads and stainless spark plugs...
