Hot-Rolled Z21210 Zinc
Hot-rolled Z21210 zinc is Z21210 zinc in the hot worked condition. The graph bars on the material properties cards below compare hot-rolled Z21210 zinc to other zinc alloys (top) 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.
