8090 aluminium alloy

8090 aluminium alloy is produced using lithium, copper and magnesium as additives. It is commonly used in aerospace due to having a lower density than 6000 or 2000 series aluminium. 8090 aluminium was developed as a replacement to 2114 and 2024 alloys and has a higher elastic modulus and lower density.

Applications
Aluminium 8090 is used in aerospace applications due to its low density; for example it is used in the AgustaWestland EH101 helicopter. 8090 can also be extruded.
