5154A-H19 Aluminum
5154A-H19 aluminum is 5154A 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 highest strength and lowest ductility compared to the other variants of 5154A aluminum.
The graph bars on the material properties cards below compare 5154A-H19 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.
