3005-H29 Aluminum
3005-H29 aluminum is 3005 aluminum in the H29 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that exceeds H28 by at least 10 MPa (or 1.5 ksi). It has the second highest strength compared to the other variants of 3005 aluminum.
The graph bars on the material properties cards below compare 3005-H29 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.
