Commercially Pure Rolled Zinc (Z15006)

Commercially pure 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 and a very low tensile strength relative to other zinc alloys. The graph bars on the material properties cards below compare commercially pure zinc to other zinc alloys (top) and the entire database (bottom).
