FAQs About Medical Grade Platinum Iridium (Pt90/Ir10) Tubes
Q: What is the exact composition and why is Pt90/Ir10 preferred for implantable medical devices?
A: Pt90/Ir10 consists of 90% platinum and 10% iridium. This balance delivers optimal biocompatibility, radiopacity, and mechanical strength while remaining cost-effective and easier to fabricate than higher-iridium alloys (e.g., Pt80/Ir20).
Q: Are these platinum iridium tubes biocompatible and compliant with medical standards?
A: Yes. Our medical grade platinum iridium tubing complies with ISO 10993 biocompatibility standards, ASTM F560 (for marker bands and related components), and ASTM B684 specifications, making it suitable for long-term human implantation.
Q: How does the radiopacity of Pt/Ir alloy benefit implantable procedures?
A: The high density of platinum-iridium provides excellent visibility under fluoroscopy and X-ray, enabling precise real-time positioning of leads, stents, and electrodes during implantation and follow-up imaging.
Q: Can platinum iridium tubes be used for both electrodes and radiopaque marker bands?
A: Absolutely. The same high-purity Pt90/Ir10 tubing is widely used to fabricate ring electrodes, marker bands (cut to short lengths), and structural components in cardiovascular, neurological, and ENT implantable devices.
Q: What is the difference between Pt90/Ir10 and pure platinum tubing for medical implants?
A: Pt90/Ir10 offers significantly higher mechanical strength, hardness, and wear resistance while retaining platinum’s biocompatibility, conductivity, and radiopacity—making it the preferred choice for demanding dynamic implant applications.
Q: Do you support custom fabrication and global supply for medical device manufacturers?
A: Yes. We provide custom cutting, machining, surface finishing, and full traceability for OEM/ODM projects worldwide, with fast lead times for medical-grade platinum iridium components.
