Platinum-Iridium (Pt-Ir) Rings are precision-engineered components
designed for laboratory and analytical equipment, offering
outstanding chemical stability, high-temperature resistance, and
mechanical durability. Typically composed of 90–97% platinum and
3–10% iridium, these rings combine platinum’s exceptional corrosion
resistance with iridium’s hardness and wear resistance, making them
ideal for high-precision instruments and long-term use in harsh
environments.
DLX manufactures Platinum Iridium Rings using vacuum induction
melting, precision forging, and fine machining processes, ensuring
high purity, dimensional accuracy, and consistent mechanical
properties. Each ring is engineered to maintain its shape, resist
chemical attack, and provide long-term performance under extreme
laboratory conditions.
