Precision Engineered Platinum Iridium Ring for High-End Scientific Instruments with High Temperature Resistance

Platinum-Iridium (Pt-Ir) Rings are high-performance components engineered for precision, durability, and chemical stability in high-end scientific instruments. Composed of 90–97% platinum and 3–10% iridium, these rings combine platinum’s excellent corrosion resistance with iridium’s hardness and wear resistance, making them ideal for laboratory, analytical, and aerospace applications.

DLX produces Platinum Iridium Rings using vacuum induction melting, precision forging, and fine machining processes, achieving high purity, tight dimensional tolerances, and consistent mechanical properties. Each ring is designed to maintain its integrity in extreme environments, ensuring reliable operation of sensitive scientific instruments over long periods.

Applications

Pt-Ir Rings are widely used in applications where chemical stability, thermal resistance, and mechanical precision are essential:

• Analytical Instruments: Mass spectrometers, gas analyzers, and electrochemical devices.

• Laboratory Equipment: High-temperature crucibles, sample holders, and precision supports.

• Thermocouples & Sensors: Protective or supporting rings for temperature probes and sensor assemblies.

• Medical Devices: Biocompatible components for diagnostic equipment and surgical instruments.

• Aerospace & Defense: High-precision measurement devices operating under extreme conditions.

• Chemical Processing: Corrosion-resistant seals, holders, and electrode supports.

Material Advantages

1. Exceptional corrosion and chemical resistance in acids and oxidizing environments.

2. High mechanical strength and wear resistance for long-term use.

3. Stable performance under high temperatures and repeated thermal cycling.

4. Superior electrical and thermal conductivity for sensor integration.

5. Non-reactive and biocompatible for medical and laboratory applications.

6. Dimensional stability with minimal thermal expansion.

7. Long operational lifespan with low maintenance requirements.

8. Precision-engineered for tight tolerances and consistent performance.

High-end scientific instruments are evolving to become more sensitive, miniaturized, and high-performing, increasing the demand for components that withstand extreme chemical, thermal, and mechanical stress. Platinum Iridium Rings are uniquely suited to meet these challenges due to their durability, corrosion resistance, and thermal stability.

In the medical and biochemical industries, Pt-Ir rings are essential in devices that contact biological fluids, ensuring safety and long-term reliability. Aerospace and defense applications similarly rely on these alloys for high-temperature, high-vacuum instrumentation.

Sustainability is also a growing factor in the industry. DLX employs a closed-loop recycling program, reclaiming platinum and iridium from scrap materials and returned components to maintain high-purity production while reducing environmental impact.
