1350-H19 Aluminum
1350-H19 aluminum is 1350 aluminum in the H19 temper. To achieve this temper, the metal is strain hardened to a strength that exceeds H18 by at least 10 MPa (or 1.5 ksi). It has the second highest strength and lowest ductility compared to the other variants of 1350 aluminum.
The graph bars on the material properties cards below compare 1350-H19 aluminum to: 1000-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.
