Our Pt90/Ir10 Platinum Iridium Alloy Tubes are designed for performance where it matters most. With a purity of 99.95%–99.99%, these tubes boast a melting point of 1800°C, a density of 21.53 g/cm³, and a tensile strength of 382 MPa. The hardness (130 HV in soft state, up to 200 HV when hardened) ensures they can handle high-stress environments without breaking a sweat. Their electrical resistivity of 24.5 µΩ·cm at 20°C makes them a solid choice for applications needing stable conductivity.
We offer these tubes in a range of forms—capillary tubes as small as 0.2 mm in diameter, standard sizes, or fully customized dimensions to fit your needs. Whether it’s a specific wall thickness or a unique length, we’ve got the flexibility to deliver. Our manufacturing process complies with ASTM B684 standards, and every tube undergoes strict quality checks to ensure it meets your expectations. We package them securely in wooden cases or padded cartons to ensure safe delivery, no matter the destination.
The 10% iridium in our Pt90/Ir10 tubes gives them an edge over lower-iridium alloys like PtIr5 or pure platinum. The extra iridium boosts mechanical strength and wear resistance, making these tubes ideal for applications where durability is critical. They’re also highly resistant to corrosion, standing up to harsh chemicals and bodily fluids with ease, which is why they’re a top pick for medical and chemical industries.

Platinum is fantastic, but adding 10% iridium takes it to another level. The higher iridium content makes our Pt90/Ir10 tubes tougher and more resistant to wear than their PtIr5 counterparts, while still maintaining platinum’s excellent corrosion resistance. Compared to materials like titanium, our tubes offer superior biocompatibility and chemical inertness, making them a better fit for sensitive applications like medical implants. Titanium is lighter and cheaper, but it can’t match the precision and longevity of Pt90/Ir10 in high-stakes environments.
Our tubes are also incredibly versatile. Need a capillary tube for a delicate medical procedure? We’ve got it. Looking for something robust for aerospace sensors? We can do that too. With our advanced manufacturing techniques, we achieve tight tolerances that ensure every tube performs flawlessly in your application.
