Aluminium Alloy 2090 is an aluminium-lithium alloy developed for low density and high stiffness-to-weight performance in aerospace-oriented applications.
Lithium additions reduce density relative to conventional high-strength aluminium alloys.
The combination of lower density and higher modulus supports lightweight design.
Developed for weight-sensitive aerospace structures.
Material selection and processing should follow the applicable alloy specification closely.
Aluminium Alloy 2090 is selected for applications that match its specific strength, corrosion, forming, machining and service characteristics.
Used for selected lightweight aerospace structures and components.
Suitable for weight-sensitive designs where stiffness and density are critical.
May be selected for specialized lightweight structural applications.
Useful where advanced aluminium-lithium alloy performance is being evaluated.
Use certified material data because alloy 2090 is more specialized than common commercial grades.
Forming and joining practices should follow the specified temper and product route.
Evaluate corrosion protection and joining compatibility during design.
No one-to-one Werkstoff number was verified for Aluminium Alloy 2090 in the cross-reference sources checked for this update, so this page does not assign a number. Confirm any proposed EN alternative against the applicable product standard and supplier certificate before substitution.
Yes. Alloy 2090 is designed as a precipitation-hardening aluminium-lithium alloy.
Corrosion performance depends on temper, processing and protection; aerospace service should be assessed specifically.
It is associated mainly with specialized aerospace and other weight-sensitive structural applications.
