Aluminium is roughly a third the weight of steel, allowing an aircraft to carry more weight and/or become more fuel efficient. Aluminium is extensively used in aircraft manufacture, and its ease of fabrication makes it an ideal choice. One particularly favoured alloy is 7075 aluminium alloy, which is often used to strengthen aircraft structures.
2022222 · Aluminium Lithium. 2099 is an aluminium lithium alloy. The addition of lithium increases the strength modulus of the aluminium alloy while lowering its density. Extrusions are available in two tempers from 0.050 to 3.00 inch (1.2 to 76mm thicknesses).
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).
