where to find 7075 alum alloy tubing?


just wondering if anyone know a resource for such tubings?

I googled a bit... it seems only alu tubing is 6063.... but I believe 7075 has much better quality/strength/stiffness than 6063 for heavy lift multirotor


thx

They do custom stuff, not sure what all they have, but worth a shot.

7075 tubing is difficult at best to get in a raw state. Look for some high altitude tent poles that climbers use. The are usually 7075,thin walled, and lite weight. Arrow shafts would be a close second option.

Hope this helped.

i did realized it is something really hard to obtain.. especially in finished part... i'll still look into it.. since it is just so good to be used for booms

thx guys..

Most models use carbon rather than aluminum. The carbon tail booms are hard to beat. I've used tent poles and arrow shafts as well but was not so concerned about the material. It would tough to optimize the weight or size of an aluminum tail boom anyhow, due to the limited sizing available.

I'm not sire about 7075 T6 but you can get 2024 T3 here http://www.onlinemetals.com/merchant.cfm?id=946&step=2, it's pretty close to 7075 T6 in terms of strength

I am actually really slow
arrow shafts are probably your best option. We use them for torque tubes on the helis all the time. work really well.
