Platinum/Iridium Alloy Rod (Pt75/Ir25)

Platinum Iridium Alloy Rod (Pt75/Ir25) offers high mechanical strength, corrosion resistance, and thermal stability in a rigid cylindrical form suited for structural, electrical, and catalytic roles in extreme environments. The rod’s geometry ensures durability under compressive and torsional loads, making it valuable for precision mechanical assemblies, high-performance connectors, and wear-resistant components in aerospace and medical systems. Industries use it for robust electrical contacts, guide pins in precision instruments, and support structures in high-temperature furnaces. In research, it is used for electrode fabrication, catalyst support studies, and durability testing under mechanical stress. The combination of Pt-Ir alloy stability with rod form strength ensures long-term reliability in applications demanding both mechanical integrity and chemical resilience.
