Zinc-Lead Rolled Zinc Alloy (Z20301)

Z20301 zinc is an otherwise-unclassified alloy of zinc. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. It has a moderately low heat capacity among zinc alloys. In addition, it has a moderately high ductility and a moderately low tensile strength.

The graph bars on the material properties cards below compare Z20301 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.
