8090 aluminium alloy explained
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.[1]
Chemical composition
| Element | Content (%) |
|---|
| Aluminium | ≥ 93 |
| Lithium | 2.2-2.7 |
| Copper | 1.0-1.6 |
| Magnesium | 0.6-1.3 | |
Applications
Aluminium 8090 is used in aerospace applications due to its low density; for example it is used in the AgustaWestland EH101 helicopter.[2] 8090 can also be extruded.[3]
