Thermal Conductivity of Common Zinc Alloys
The thermal conductivity of zinc alloys can vary depending on the specific alloy composition. In general, zinc alloys have moderate to low thermal conductivity compared to some other metals. The following table provides a curated list of thermal conductivity values for different zinc alloys at room temperature (approximately 20°C or 68°F).
