High-Purity Pt90Ir10 Tubes – Platinum-Iridium Small-Diameter Tubing for Global Markets

Product Description

Pt90Ir10 Tubes are precision-fabricated tubing composed of a platinum-iridium alloy with nominal composition 90% platinum and 10% iridium (Pt 90/Ir 10). This alloy tube is engineered for applications demanding exceptional chemical inertness, high temperature stability and robust mechanical performance in harsh service environments. With melting point around 1800 °C, density ~21.56 g/cm³, and tensile strength in the 380–620 MPa range, Pt90Ir10 tubing offers a unique combination of corrosion resistance, high purity and dimensional integrity. Whether used in aerospace propulsion systems, medical implants, high-temperature furnace assemblies or ultra-clean fluid transport in chemical processing, these Pt90Ir10 Tubes deliver reliable performance where conventional alloys fail.

Typical Specifications & Performance Parameters

Below is a representative specification table for Pt90Ir10 Tubes. Actual values may vary depending on manufacture route, temper and size.

Standards & Execution: The Pt90Ir10 Tubes are produced in accordance with precious-metal tubing practices, with material certification (chemical and physical) available, and often meet standards such as ASTM B684 for platinum-iridium alloys, or equivalent premium alloy specifications.

Application Areas

The Pt90Ir10 Tubes are highly suited for a variety of demanding applications across global markets:

• Chemical processing: Used for ultra-pure fluid or gas delivery in corrosive media, thanks to excellent chemical inertness.

• Medical & biomedical devices: Ideal for long-term implantable leads, electrode housings and micro-tubing in neurostimulation or cardiac systems (especially relevant for South-East Asia, Middle East medical device OEMs).

• Aerospace & propulsion: Suitable for high-temperature thermocouple sheaths, sensor housings and small structural tubing in jet-engine components.

• Electronics & instrumentation: High-purity micro-tubing for high-end sensors, connectors and microscale precision devices.

• Research & advanced energy: Fuel-cell components, high-temperature reactors, and instrumentation in North America and Europe that demand both chemical stability and purity.

Frequently Asked Questions (FAQ)

Q1: What makes Pt90Ir10 Tubes different from standard platinum tubing?
A1: The addition of 10% iridium significantly increases mechanical strength and high-temperature stability compared with pure platinum, while retaining platinum’s superior corrosion resistance and chemical inertness. As a result, Pt90Ir10 Tubes are better suited for extreme environments.

Q2: Can I get custom diameters or wall thicknesses for Pt90Ir10 Tubes?
A2: Yes — many producers offer custom OD/ID and wall thickness specifications (for example OD 0.3 mm minimum, wall thickness as low as 0.015 mm in capillary versions) tailored for micro-fluidic or implantable device use.

Q3: What are the supply and sourcing considerations for Pt90Ir10 Tubes in markets such as Middle East or South Asia?
A3: Given that platinum and iridium are premium precious metals, price and material availability can fluctuate. Buyers in South Asia, Southeast Asia or Middle East should plan delivery lead-times and check certification, tubing tolerances, and ensure the supplier can provide full traceability and quality certificates. Investing in the correct specification up front ensures long-term reliability in harsh service.

Q4: How do I verify quality and performance of Pt90Ir10 Tubes?
A4: Request a Certificate of Analysis (COA) with actual chemical composition (Pt/Ir ratio), tensile/hardness test results, dimensional tolerances, and material condition (annealed, as-drawn). Cross-check with industry references: for example, Pt90Ir10 alloy is documented with hardness ~130-190 HB and tensile ~380-620 MPa.
