Aluminum 7075 Tubing, Bar, Sheet and Plate
Aluminum 7075 Tubing is capable of high strength when developed by heat treating. Aluminum 7075 Tubing also has excellent properties at low temperatures. Aluminum 7075 Tubing is commonly used in the manufacture of aircraft and other aerospace applications not requiring the corrosion resistance of Clad 7075. It is best to machine Aluminum 7075 Tubing in the annealed condition and oil lubricants should be used. Aluminum 7075 Tubing is comparatively strong for an aluminum alloy. It produces greater springback during forming operations.
If difficulty is encountered when forming, then warming the Aluminum 7075 Tubing to 200 - 250 F will assist formability. Resistance welding is the only preferred method of joining Aluminum 7075 Tubing. The aluminum may then be given a precipitation hardening (aging) heat treatment. Aluminum 7075 Tubing may be forged in the temperature range of 900 F to 700 F. Aluminum 7075 Tubing may be solution annealed at 900 F for 2 hours at temperature, followed by a water quench.
Cold working is readily accomplished with Aluminum 7075 Tubing in the soft, annealed, condition. Conventional forming methods may be used, but springback is greater for this alloy than for other of the aluminum alloys. The temperature for annealing Aluminum 7075 Tubing is 775 F, holding at temperature for 3 hours. Controlled cooling at 50 F per hour should then be used down to 500 F from which it can then be air cooled. Precipitation strengthening (aging) of Aluminum 7075 Tubing is done at 250 F for 24 hours and air cooled.
