Pt-Ir Alloy Capillary Tubes for Analytical Instruments

High-temperature industrial processes demand materials that combine strength, chemical resistance, and precise dimensional stability. Platinum Iridium Tubes DIN 17744 from DLX deliver this combination, offering unmatched performance for industrial applications where failure is not an option.

Platinum-iridium alloys, typically Pt90Ir10 or Pt80Ir20, provide a synergy of platinum’s corrosion resistance and iridium’s hardness and high-temperature strength. Tubes manufactured to DIN 17744 standards ensure consistent dimensions, structural integrity, and surface quality.

DLX employs vacuum induction melting and precision tube drawing techniques to produce ultra-pure, homogeneous Pt-Ir tubes. This process ensures tight tolerances, smooth surfaces, and superior mechanical properties, critical for industrial high-temperature applications.
