2099 Aluminium Lithium

Low density and high stiffness

For high-strength applications.


Introducing 2099 Aluminium-Lithium alloy - a product developed for use in motorsport, aerospace and high-strength applications requiring low density, high stiffness, superior damage tolerance & excellent corrosion resistance. Lithium additions increase the strength and modulus of Al alloys while lowering their density. Alloy 2099 extrusions are available in various temper conditions including T83, T86 , T852 & T8. Other tempers are available on request. Alloy 2099-T83 offers strength and excellent corrosion resistance with moderate fracture toughness.

Toughness & Fatigue:

Fatigue crack growth resistance and S/N fatigue performance also show improvement vs 2024-T3511, a standard product for applications considered fatigue critical. The alloy shows significant improvement when compared to 2219 in elevated temperature.

Corrosion Resistance:

The corrosion resistance of Alloy 2099 is much better than 7075-T6511 and 2024-T3511 with both the T8E67 and T83 tempers receiving EA (mild exfoliation) or better exfoliation ratings compared to the conventional alloys ED (very severe exfoliation). The stress-corrosion cracking performance is also much improved.

Suitability:

Alloy 2099 extrusions can replace 2xxx, 6xxx, and 7xxx, aluminium alloys in various applications. Examples include engineering areas where stiffness or statically and dynamically load performance are critical.
