Formula: Pt 85/Ir 15
Form: Wire
Material: Platinum/Iridium Alloy
Commodity: Precious Metals
Diameter: 1mm
Temper: As Drawn
Platinum/Iridium Alloy Spooled Wire (Pt85/Ir15) is a precious metal wire produced by Goodfellow within their range of specialty alloy products. With a high melting point and excellent corrosion resistance, this wire combines the durability of platinum with the hardness of iridium. It can withstand high temperatures, making it ideal for use in electrical components, thermocouples, and high-temperature furnace windings. The addition of iridium also improves the mechanical strength and creep resistance compared to pure platinum wire.
