Density of Common Platinum Alloys
The density of platinum alloys can vary depending on the specific composition of the alloy. In general, platinum and its alloys are known for their high density. These alloys are commonly used in jewelry, industrial applications, and as catalysts due to their desirable properties such as high melting points, corrosion resistance, and catalytic activity.
The following table provides a list of density values for various platinum alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
