8090 aluminium alloy
From Wikipedia, the free encyclopedia
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.[citation needed] 8090 aluminium was developed as a replacement to 2114 and 2024 alloys and has a higher elastic modulus and lower density.[1]
