Zinc-Low Copper Rolled Zinc Alloy (Z40101)

Z40101 zinc is an otherwise-unclassified alloy of zinc. It is typically furnished in 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).
