Description

Iridium is a rare, dense, and corrosion-resistant platinum group metal (PGM) with the atomic number 77. Its exceptional chemical stability and high melting point make it a critical material for demanding high-performance and high-temperature applications. This metal is essential for manufacturers and researchers in sectors requiring superior durability and catalytic activity, such as advanced electronics, specialized chemical processing, and high-end scientific instrumentation.

Application

• Catalyst Production: Used in catalysts for nitric acid production, hydrogenation reactions, and in high-performance electrodes for electrolysis.
• Electronics & Electrical Contacts: Critical for spark plug electrodes, crucibles for growing single crystals (e.g., sapphire), and high-reliability electrical contacts.
• Medical & Biomedical Devices: Employed in radiotherapeutic cancer treatment devices (as a radioisotope source) and in biocompatible electrodes for implants.
• Chemical Process Equipment: Fabricated into laboratory crucibles, spinnerets for synthetic fiber production, and other components requiring extreme corrosion resistance.
• Scientific Research: Serves as a standard for weight and measure (e.g., the international prototype kilogram was made from a platinum-iridium alloy) and in specialized analytical equipment.
• Additive Manufacturing & Coatings: Used in powder form for 3D printing of high-value components and applied as a protective coating for extreme environments.
