2099 Aluminium Lithium2099 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).

Alloy 2099-T83

High strength and excellent corrosion resistance with moderate fracture toughness.

Alloy 2099-T8E67

Lower strength but very high fracture toughness and excellent fatigue crack growth resistance.

Alloy 2099 extrusions have been available since the mid 2000's and have been specified for use on many commercial aircraft and helicopter programs.

Key Features:

2099 aluminium lithium alloy is a low density material with high stiffness. With superior damage tolerance and excellent corrosion resistance, the alloy offers excellent weldability.
