Electrical Resistivity of Common Platinum Alloys

The electrical resistivity of platinum alloys can vary depending on the specific composition of the alloy. Generally, platinum and its alloys exhibit relatively low electrical resistivity compared to many other materials.

The following table provides a comprehensive list of electrical resistivity values for common platinum alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
