3005-H27 Aluminum
3005-H27 aluminum is 3005 aluminum in the H27 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly 7/8 of the way between annealed (O) and full-hard (H28).
The graph bars on the material properties cards below compare 3005-H27 aluminum to: 3000-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.
