Platinum/Iridium Alloy Rod (Pt90/Ir10)

Platinum Iridium Alloy Rod (Pt90/Ir10) combines platinum’s chemical inertness and catalytic ability with iridium’s strengthening effect in a robust cylindrical geometry designed for demanding mechanical and thermal environments. The rod form allows for use in precision-engineered fixtures, high-wear electrical contacts, and stable supports for high-temperature systems. Industries employ it in furnace components, aerospace instrumentation mounts, and biomedical implants where structural integrity and corrosion resistance are paramount. Research uses include high-precision electrode fabrication, wear-resistance testing, and studies of thermal expansion stability in high-performance alloys. The combination of noble metal properties and the mechanical resilience of the rod format ensures exceptional reliability in both industrial operations and advanced experimental setups.
