Overview of Precision Platinum Iridium Pt-Ir Capillary Tubing
In the demanding field of Medical Electronics & Precision Components, our Premium Platinum Iridium Pt-Ir Capillary Tubing delivers the ultimate combination of high density, corrosion resistance, and fluoroscopic visibility. Manufactured from medical-grade Pt90/Ir10 alloy (ASTM B684 compliant, purity ≥99.95%), these seamless, thin-walled capillary tubes serve as the raw material for cutting ultra-precise radiopaque marker bands used in catheters, vascular stents, and minimally invasive interventional devices.
Engineered for tight tolerances (OD/ID/WT ±0.01 mm typical), the tubing ensures burr-free cutting and flawless integration into next-generation catheter assemblies, stent delivery systems, and biomedical sensors. Its superior radiopacity under X-ray and fluoroscopy enables real-time visualization during angioplasty, electrophysiology procedures, and neurovascular interventions — critical for precision placement in high-stakes medical electronics applications.

FAQs on Medical Grade Platinum-Iridium Tubes
Q1: What is the standard alloy composition for your Pt-Ir capillary tubing?
A: Pt90/Ir10 (90% platinum, 10% iridium) – the industry gold standard for radiopaque marker bands due to optimal balance of radiopacity, biocompatibility, and mechanical properties.
Q2: Are these capillary tubes suitable for cutting radiopaque marker bands?
A: Yes. Designed specifically for high-precision cutting into marker bands (lengths down to 0.2 mm) with burr-free results for catheter and stent applications.
Q3: What tolerances can you achieve on OD, ID, and wall thickness?
A: Typical tolerance ±0.01 mm (0.0004") on critical dimensions; tighter tolerances available upon request for ultra-precision medical electronics components.
Q4: Is the tubing biocompatible and compliant with medical standards?
A: Fully biocompatible, meets ASTM B684, and supplied with material certification suitable for FDA-regulated and CE-marked medical device manufacturing.
Q5: Why choose Platinum Iridium over tantalum or gold for marker bands?
A: Pt-Ir provides superior radiopacity, better long-term corrosion resistance, and excellent electrical conductivity for combined marker + electrode applications in interventional cardiology.
