Density of Common Zinc Alloys
The density of zinc alloys can vary depending on the specific alloy composition. However, commonly used zinc alloys have densities ranging from 6600 to 7200 kg/m3. These alloys are known for their relatively low density compared to other metals, making them suitable for applications where lightweight yet durable materials are required.
The following table provides a list of density values for different zinc alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
