Zinc-Low Copper Rolled Zinc Alloy (Z40101)
Z40101 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 fairly low tensile strength and a moderately high ductility.
The graph bars on the material properties cards below compare Z40101 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.
