Precision PtIr Alloy, (PtIr10 tips, PtIr20 rings,) & Component for Cardiac & Neuromodulation Devices

We are a dedicated contract manufacturer specializing in platinum‑iridium (PtIr) alloy precision components for the global medical device market. we focus exclusively on the demanding requirements of implantable cardiac rhythm management, neuromodulation, electrophysiology, and interventional catheters – applications where material purity, dimensional accuracy, and long‑term in‑vivo performance are non‑negotiable.

Our core competency lies in the micro‑machining of PtIr alloys – including PtIr10 (90% Pt / 10% Ir), PtIr20, and other custom ratios – to tolerances as tight as ±0.001 mm. With years of experience in processing precious metals, we have mastered the unique challenges of PtIr: its high hardness, work‑hardening tendency, and the need for impeccable surface finish. Today, we supply critical components to leading medical OEMs in the US and Europe, helping them bring safe, reliable, and innovative therapies to patients worldwide.

Platinum‑iridium alloys are the gold standard for active implantable and interventional devices because they uniquely combine: Exceptional biocompatibility – inert in body fluids, minimal ion release, and low thrombogenicity. High electrical conductivity – essential for low‑impedance signal transmission and efficient energy delivery. Radiopacity – clearly visible under X‑ray and fluoroscopy, enabling precise image‑guided placement.

Outstanding corrosion resistance – withstands aggressive physiological environments and repeated sterilization. Mechanical strength – iridium additions significantly increase hardness and wear resistance over pure platinum, ensuring long‑term structural integrity. These properties make PtIr the preferred material for stimulating electrodes, ablation tips, marker bands, connector pins, and feedthrough terminals.

We maintain full in‑process inspection with CMM, optical comparators, and surface profilometers, ensuring every batch meets your drawing specifications. Our typical production runs from prototypes to high‑volume series with on‑time delivery rates exceeding 98%.
