7075 is capable of high strength as developed by heat treating. It also has excellent properties at low temperatures.
Machinability: It is best to machine this alloy in the annealed condition. Machining capability is good and oil lubricants should be used.
Welding: Resistance welding is the only preferred method of joining AL 7075 alloy. Gas welding should be avoided and use of arc welding may result in degradation of corrosion resistance.
