2024-T361 Aluminum
2024-T361 aluminum is 2024 aluminum in the T361 temper. The graph bars on the material properties cards below compare 2024-T361 aluminum to: 2000-series alloys (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.
