Equivalent materials to aluminium / aluminum 2117 alloy are:
- AMS 7222
- ASTM B316
- QQ A-430
- SAE J454
Machinability of aluminium / aluminum 2117 alloy is good in the T4 condition; however machining is difficult in the annealed condition. The use of oil lubricant is recommended for all processes. This alloy has very good workability with hot and cold working. Hot working should be performed at 426-343°C (800 to 650°F). Both should be performed with the alloy in T4 or O (annealed) conditions.
Welding of aluminium / aluminum 2117 alloy can be performed using TIG or MIG methods. It is recommended that the filler rod be of the same alloy. Forging should be carried out 521-343°C (970-650°F). Likewise annealing should be performed at 412°C (775°F) for 3 h followed by controlled cooling at 10°C (50 °F)/h down to 260°C (500 °F). Finally, it should be air cooled.
ApplicationsAluminium / aluminum 2117 alloy is chiefly used in the manufacture of a variety of mechanical fasteners among other products. It is also used for making rivets.
