5042-H39 Aluminum
5042-H39 aluminum is 5042 aluminum in the H39 Temper. The graph bars on the material properties cards below compare 5042-H39 aluminum to: 5000-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.
