Our Pt80/Ir20 Platinum Iridium Tubes are engineered for durability and precision. With a purity of 99.95%–99.99%, these tubes boast a melting point of 1820°C, a density of 21.60 g/cm³, and a tensile strength of 450 MPa. Their hardness (170 HV in soft state, up to 250 HV when hardened) ensures they can handle intense mechanical stress, while their electrical resistivity of 28.0 µΩ·cm at 20°C supports reliable conductivity for spark plug electrodes.

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 strength—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 top-notch performance. We package them securely in padded cartons or wooden cases for safe delivery worldwide.

The 20% iridium content in our Pt80/Ir20 tubes makes them exceptionally tough. This high iridium ratio enhances strength and wear resistance compared to PtIr10 or pure platinum, making them ideal for spark plug electrodes exposed to high temperatures and corrosive combustion byproducts. They also resist chemical degradation, ensuring long-term reliability in demanding environments.

Platinum is great, but adding 20% iridium takes our Pt80/Ir20 tubes to the next level. The higher iridium content boosts mechanical strength and wear resistance, making them tougher than PtIr10 or pure platinum tubes. Compared to nickel alloys, our tubes offer superior corrosion resistance and conductivity, critical for spark plug electrodes in high-performance engines. While nickel alloys are cheaper, they can’t match the durability or precision of Pt80/Ir20 in extreme conditions like automotive or aerospace applications.

Customization is where we excel. Need a capillary tube for a sensor electrode? We can make it happen. Want a specific length for a spark plug component? No problem. Our advanced manufacturing techniques, like precision extrusion and laser machining, ensure tight tolerances that meet the strictest industry standards.
