Aluminium 2017 is a heat treatable wrought alloy that offers intermediate strength, fair corrosion resistance, and good machining characteristics with ductility and formability better that aluminium 2014. 2017 alloy is suitable for welding only by resistance welding.
2017 alloy has excellent machinability in the T4 temper and formability is excellent especially in the annealed condition. 2017 aluminium alloy can be solution annealed at 504°C (940°F) for 3-4h followed by water quenching. Annealing can be performed at 413°C (775°F) for 3 h and then controlled cooling at 10°C (50°F)/h down to 260°C (500° F). Cold working such as shaping and bending, can be easily performed.
Because of its unique properties, 2017 aluminium is used for a number of different applications including: high strength structural components, aircraft, transportation, machine construction, rivets, gauges and military equipment.
