Yes, we produce 7075T6511 aluminum tubes. Compared with T6 temper, T6511 aluminum is stress-relieved by stretching. 7075T6511 aluminum tubes are commonly used in aircraft and aerospace. No matter alloy composition, or mechanical properties, our 7075T6511 aluminum tubes are all beyond our National Standard, and also can meet standard AMSQQA200/11 and AMS4169.
