Electrical Resistivity of Common Zinc Alloys
The electrical resistivity of zinc alloys varies depending on their composition and specific alloying elements. In general, zinc itself is a relatively good conductor of electricity compared to other metals, but the addition of alloying elements can significantly alter its electrical properties.
The following table provides a comprehensive list of electrical resistivity values for common zinc alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
