8090-T852 Aluminum

8090-T852 aluminum is 8090 aluminum in the T852 temper. To achieve this temper, the metal is solution heat-treated, stress relieved, then artificially aged. The stress relief is accomplished by compressing the metal by 1-5%.

The graph bars on the material properties cards below compare 8090-T852 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.
