8090-T8151 Aluminum
8090-T8151 aluminum is 8090 aluminum in the T8151 temper. The graph bars on the material properties cards below compare 8090-T8151 aluminum to: otherwise unclassified aluminums (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
