Our Platinum Iridium Tubes are built for precision and durability. With a purity of 99.95%–99.99%, these tubes deliver exceptional performance. The PtIr10 alloy has a melting point of 1800°C, a density of 21.53 g/cm³, and a tensile strength of 382 MPa, while PtIr5 offers a melting point of 1790°C, a density of 21.49 g/cm³, and a tensile strength of 274 MPa. Their hardness (130 HV for PtIr10, 90 HV for PtIr5 in soft state) ensures they can handle mechanical stress, and their electrical resistivity (24.5 µΩ·cm for PtIr10, 19.0 µΩ·cm for PtIr5 at 20°C) makes them ideal for electrical contacts.

We offer these tubes in a range of forms, from capillary sizes with outer diameters as small as 0.2 mm to larger tubes for robust applications. Customization is our forte—whether you need a specific wall thickness or length, we tailor our tubes to your exact specs. Our manufacturing process complies with ASTM B684 standards, and every tube undergoes rigorous quality checks to ensure reliability and performance. We package them securely in padded cartons or wooden cases for safe delivery worldwide.

The platinum-iridium alloy’s low resistivity and corrosion resistance make it perfect for electrical contacts. The iridium content enhances strength, giving our tubes an edge over pure platinum or copper in high-reliability applications. They resist harsh chemicals and high temperatures, ensuring long-term performance in demanding environments.

Platinum is solid, but adding iridium makes our tubes a cut above. The 10% iridium in PtIr10 boosts strength and wear resistance, while PtIr5 offers a slightly softer, more flexible option. Both alloys outperform copper in corrosion resistance, critical for electrical contacts exposed to harsh conditions. Compared to stainless steel, our tubes provide better conductivity and durability, making them ideal for high-stakes applications like electrochemical electrodes. While copper is cheaper and highly conductive, it corrodes easily, whereas our platinum-iridium tubes deliver long-term reliability.

Customization sets us apart. Need a capillary tube for a sensor electrode? We can make it happen. Want a specific length for a circuit component? No problem. Our advanced manufacturing techniques, like precision drawing and laser machining, ensure tight tolerances that meet the strictest industry standards.
