Product Details

The Premium Platinum Iridium Ring from DLX is a specialized component crafted from platinum-iridium (Pt-Ir) alloy, renowned for its exceptional balance of strength, corrosion resistance, and thermal stability. Composed typically of 90% platinum and 10% iridium, this alloy ring exhibits a high melting point exceeding 1700°C, making it indispensable in extreme conditions. Unlike standard metal rings, our Pt-Ir rings resist chemical attack, oxidation, and mechanical wear, providing a reliable seal or structural element in harsh industrial settings. As a trusted platinum iridium ring manufacturer, DLX ensures each ring meets ASTM and ISO standards, with customizable dimensions for seamless integration into your systems. Optimize your operations with this premium corrosion-resistant ring solution—contact us today for bulk orders and competitive pricing.

DLX's Premium Platinum Iridium Rings are designed with cutting-edge metallurgy to outperform conventional materials. Key features include:
Withstands aggressive chemicals and environments, reducing degradation rates by up to 58% compared to pure platinum, ideal for acidic or alkaline exposures.
Enhanced hardness (up to 135 Vickers) from iridium alloying ensures minimal abrasion and extended service life in high-friction applications.
Maintains structural integrity at temperatures over 1700°C, with outstanding oxidation and creep resistance for reliable operation in thermal cycling.
Non-magnetic and hypoallergenic properties make it perfect for medical implants and diagnostic equipment, surpassing stainless steel in corrosion-proofing.
Available in seamless designs with diameters from 5mm to 200mm, tolerances ±0.01mm, and surface finishes for optimal sealing efficiency.
High density (21.5 g/cm³) provides robustness without brittleness, combining platinum's ductility with iridium's strength for versatile use.


Versatile and robust, the Premium Platinum Iridium Ring excels in diverse sectors where reliability is non-negotiable. Key applications include:
Used as sealing rings in jet engines and rocket nozzles to prevent gas leaks under extreme pressures.
Essential for pacemaker leads, surgical implants, and diagnostic equipment requiring biocompatible seals.
Provides hermetic sealing in vacuum tubes, sensors, and high-vacuum systems to protect sensitive circuits.
Employed in reactors and pipelines for its resistance to aggressive media in petrochemical plants.
Ideal for high-temperature crucibles, thermocouples, and precision instruments in scientific experiments.
Leverages aesthetic appeal and durability for high-end sealing elements in luxury watches and instruments.
