Formula: Pt 75/Ir 25
Form: Wire
Material: Platinum/Iridium Alloy
Commodity: Precious Metals
Diameter:
0.05mm
Temper:
Annealed
This Pt/Ir alloy wire combines the corrosion resistance and high-temperature durability of platinum with the hardness and mechanical strength of iridium. With excellent ductility and conductivity, it is widely used in high-temperature thermocouples, electrical contacts, and electrodes for glass manufacturing. The spooled wire format allows for continuous, consistent feeding during precision wire drawing, welding, or winding operations. This specialty alloy wire is part of Goodfellow's diverse range of high-performance spooled wire products.
