Our Platinum Iridium Alloy Tubes are engineered for precision and toughness. With a purity of 99.95%–99.99%, these tubes offer 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 provides 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) supports stable conductivity for thermocouple applications.

We offer these tubes in various forms, from capillary sizes with outer diameters as small as 0.2 mm to larger tubes for robust thermocouple designs. 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 accuracy and reliability. We package them securely in padded cartons or wooden cases for safe delivery worldwide.

The platinum-iridium alloy’s thermal stability and corrosion resistance make it perfect for thermocouples. The iridium content enhances strength, giving our tubes an edge over pure platinum or nickel alloys in high-temperature environments. They resist harsh chemicals and extreme heat, ensuring consistent performance in demanding applications.

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 nickel alloys in thermal stability and corrosion resistance, critical for thermocouples in aerospace or chemical processing. Compared to stainless steel, our tubes provide better conductivity and durability, making them ideal for high-precision temperature measurements. While nickel alloys and stainless steel are cheaper, they can’t match the longevity or accuracy of our platinum-iridium tubes in extreme conditions.

Customization sets us apart. Need a capillary tube for a high-temperature sensor? We can make it happen. Want a specific length for an industrial furnace thermocouple? No problem. Our advanced manufacturing techniques, like precision extrusion and laser machining, ensure tight tolerances that meet the strictest industry standards.
