Our Platinum Iridium Capillary Tubes are engineered for precision and durability. With a purity of 99.95%–99.99%, these tubes are designed to handle extreme conditions. The PtIr5 alloy has a melting point of 1790°C, a density of 21.49 g/cm³, and a tensile strength of 274 MPa, while the PtIr10 version steps it up with a 1800°C melting point, 21.53 g/cm³ density, and 382 MPa tensile strength. Their hardness (90 HV for PtIr5, 130 HV for PtIr10 in soft state) ensures they hold up under stress, and their electrical resistivity (19.0 µΩ·cm for PtIr5, 24.5 µΩ·cm for PtIr10 at 20°C) makes them ideal for sensor applications requiring stable conductivity.
These capillary tubes are available in ultra-fine sizes, with outer diameters as small as 0.2 mm and customizable wall thicknesses and lengths. Whether you need a tube for micro-fluid transfer in a medical sensor or a robust component for aerospace, we can tailor it to your exact specs. Our manufacturing process adheres to ASTM B684 standards, and every tube undergoes rigorous quality checks to ensure flawless performance. We package them securely in padded cartons or wooden cases to guarantee safe delivery, no matter where you are.
The corrosion resistance of our Platinum Iridium Capillary Tubes is a game-changer. They stand up to harsh chemicals, high temperatures, and even bodily fluids, making them perfect for sensitive applications. The iridium content enhances mechanical strength, giving them an edge over pure platinum or other materials like stainless steel, especially in high-precision sensor systems.

Platinum is great, but blending it with iridium makes it exceptional. The 5% or 10% iridium in our PtIr5 and PtIr10 tubes boosts strength and wear resistance, making them ideal for demanding sensor applications. Compared to stainless steel, our tubes offer superior corrosion resistance and biocompatibility, critical for medical and chemical sensors. While stainless steel is cheaper, it can’t match the precision and longevity of our platinum-iridium alloy in harsh environments. Even compared to pure platinum, our tubes provide better mechanical properties, ensuring they hold up under stress without compromising performance.
Customization is where we shine. Need a capillary tube with a specific inner diameter for a gas sensor? We’ve got you covered. Want a particular length for a medical diagnostic device? No problem. Our advanced manufacturing techniques allow us to achieve tight tolerances, ensuring every tube meets your exact requirements.
