Precision Engineered Pt-Ir Alloy Ring with Corrosion Resistance and High

Product Specification

Platinum-Iridium (Pt-Ir) Alloy Rings are engineered for precision, durability, and chemical stability in demanding sensor and connector applications. Typically composed of 90–97% platinum and 3–10% iridium, these rings combine platinum’s outstanding corrosion resistance with iridium’s hardness and wear resistance, making them ideal for high-end sensors, connectors, and precision electrical components.

DLX produces Pt-Ir Alloy Rings using vacuum induction melting, precision forging, and fine machining, resulting in high-purity material, uniform microstructure, and tight dimensional tolerances. The rings are designed to maintain performance under mechanical stress, thermal cycling, and corrosive environments, ensuring long-term reliability for critical applications.

Pt-Ir Alloy Rings are widely applied in areas that require chemical stability, electrical precision, and mechanical reliability:

• Sensor Manufacturing: Load cells, pressure sensors, and thermocouples requiring precise mechanical support.

• Connector Components: Electrical connectors in aerospace, medical, and industrial equipment.

• High-Temperature Electronics: Protective or supporting rings for probes and micro-electronic assemblies.

• Laboratory Instruments: Analytical devices, micro-actuators, and electrode supports.

• Medical Devices: Biocompatible components for surgical tools and implantable sensors.

• Aerospace & Defense: Precision instrumentation components exposed to extreme conditions.
