Zirconium Disk

Zirconium Disk offers exceptional corrosion resistance, high ductility, and excellent thermal stability, making it a reliable choice for environments exposed to aggressive chemicals or high temperatures. The flat, circular geometry ensures even contact surfaces, critical in electrochemical testing, sealing applications, and precision machining. Industries such as chemical processing, marine engineering, and research laboratories use zirconium disks for electrode substrates, corrosion testing coupons, and gasket components. Specific applications include electrochemical sensors, sealing elements for harsh chemical environments, and calibration standards for material performance evaluation. In research, zirconium disks are frequently employed to study surface passivation, galvanic behavior, and compatibility with advanced coatings. Their combination of resilience and geometric precision makes them valuable for both applied engineering and materials science studies.
