Platinum-Iridium (Pt-Ir) Alloy Tubes are premium materials engineered for applications that demand exceptional chemical stability, high-temperature resistance, and mechanical reliability. Typically composed of 90–97% platinum and 3–10% iridium, these tubes combine platinum’s corrosion resistance with iridium’s enhanced hardness, ensuring long-term performance in harsh laboratory, industrial, and aerospace environments.
DLX produces Pt-Ir Alloy Tubes using vacuum induction melting, precision extrusion, and cold drawing to achieve tight dimensional tolerances, uniform microstructure, and superior purity. These tubes are particularly suitable for thermocouples, reference electrodes, and high-temperature laboratory equipment, where both chemical inertness and mechanical stability are essential.
Pt-Ir Alloy Tubes are widely used in precision industries, including:
Thermocouples: Protective sheaths for high-temperature thermocouples used in furnaces, turbines, and chemical processing.
Electrodes: Reference and working electrodes in electrochemical and analytical applications.
Laboratory Equipment: Crucibles, electrodes, and high-temperature gas sensors.
Aerospace: Temperature sensors and instrument components operating under extreme conditions.
Medical Devices: Components for surgical and diagnostic instruments requiring biocompatibility.
Energy Industry: High-temperature probes and corrosion-resistant measurement devices.
Excellent corrosion and chemical resistance in acids, oxidizing atmospheres, and high-temperature gases.
Stable mechanical properties across a wide temperature range (up to 1800°C).
Superior hardness and wear resistance compared to pure platinum.
High electrical conductivity suitable for electrochemical applications.
Non-reactive and biocompatible, ideal for medical and lab applications.
Dimensional stability with minimal thermal expansion.
Long service life with minimal degradation under repeated thermal cycling.
Compatible with microfabrication and precision forming processes.
The use of Pt-Ir alloy tubes in thermocouples and electrodes continues to grow as industries demand higher-precision sensors and longer-lasting laboratory equipment. Miniaturization of sensors in aerospace, energy, and medical technologies increases the need for tubes with consistent mechanical properties and corrosion resistance.
In the medical and analytical sectors, the shift toward implantable and long-life devices requires alloys that are both biocompatible and mechanically robust. Pt-Ir alloys fulfill these requirements, offering superior fatigue resistance and stable electrical conductivity.
Meanwhile, sustainability and resource efficiency have become key factors. DLX has implemented a closed-loop recycling system for platinum and iridium scrap, reducing environmental impact while maintaining alloy purity. This eco-conscious approach is increasingly valued in research and industrial markets globally.
