Zinc Alloy Specifications

Flexability - Versitility - Design Complexity

Zinc alloy specifications are laid out in the three tables on this page. The first table provides information on the mechanical properties of two different zinc alloys, including tensile and yield strength. The second table indicates the physical properties of the same alloys, including density and electrical conductivity. The final table provides the actual chemical breakdown of the zinc alloy specifications.
