High-Precision Platinum Iridium Alloy Ring for Medical and Aerospace Application

Product Specification

Platinum Iridium alloy (Pt-Ir) is a high-performance noble metal material known for its excellent corrosion resistance, electrical stability, and mechanical strength. It typically contains 5% to 30% iridium, which greatly enhances the hardness and wear resistance of platinum. Common grades include Pt5Ir, Pt10Ir, Pt20Ir, and Pt30Ir. These alloys maintain outstanding mechanical and chemical stability, even under extreme environments such as high temperatures, vacuum, and acidic conditions.

At DLX, we produce platinum iridium alloy rings, tubes, and springs using precision melting and forming technology. Our alloys meet strict international standards such as ASTM B684 (U.S.), DIN 17744 (Germany), and ISO 11490 (Europe), ensuring consistent purity, density, and performance across every batch.

Applications

Platinum Iridium alloy rings are used in high-precision and high-reliability industries:

• Medical Industry: Used for implantable components, pacemaker contacts, and surgical instruments due to biocompatibility.

• Aerospace: Ideal for sensors, jet engine components, and thermocouple parts because of stability at high temperatures.

• Electronics: Applied in precision connectors, electrodes, and switches requiring consistent conductivity.

• Laboratory Instruments: Used in crucibles, thermocouples, and analytical equipment for their resistance to oxidation and contamination.

• Jewelry & Watches: Preferred for luxury products requiring a balance of beauty, durability, and wear resistance.

Industry Trend

Global demand for platinum group metals is increasing due to the expansion of aerospace, semiconductor, and medical device industries. The Pt-Ir alloy market is shifting toward miniaturization and higher precision. Manufacturers are focusing on tighter dimensional tolerances, improved surface finishes, and enhanced purity levels.

At the same time, the sustainability trend is driving recycling and reclaiming processes for precious metals, making suppliers with in-house refining capability—like DLX—more competitive.

Article: Platinum Iridium Alloy Ring — The Benchmark for Precision and Reliability

Platinum Iridium alloys have a long history in precision engineering. Originally developed for standard weights and measurement instruments, this material has evolved into one of the most advanced functional metals for aerospace and medical use. Its combination of strength, corrosion resistance, and conductivity makes it indispensable in fields where reliability defines success.

At DLX, we have mastered the art of Pt-Ir alloy processing. Every ring starts from high-purity platinum and iridium metals that are vacuum melted to eliminate impurities. The molten alloy is then forged and rolled under strict temperature control to achieve fine grain uniformity. After forming, each ring undergoes heat treatment, mechanical testing, and microscopic inspection to ensure it meets international aerospace and medical standards.

Our clients value DLX not just for material quality, but for engineering precision. We understand that a single component, such as a thermocouple ring or medical electrode, can determine the safety and accuracy of an entire system. Therefore, our team ensures that each piece delivers consistent electrical stability, dimensional accuracy, and long-term durability.

In the current market, where manufacturers are pushing for smaller, lighter, and more efficient components, DLX’s advanced alloy refining and forming capabilities make us a reliable long-term partner. Our products combine metallurgical innovation with craftsmanship — the result is a platinum iridium alloy ring that performs with precision and endurance, even under the most demanding conditions.

From concept to delivery, DLX provides complete technical support — including alloy design, machining, and surface finishing. Whether you need Pt10Ir for medical electrodes or Pt20Ir for aerospace sensors, we deliver consistent quality backed by years of metallurgical expertise.

Choosing DLX means choosing a manufacturer that doesn’t just supply metal — we deliver performance, reliability, and trust.
