Iridium Foil/Strip/Ribbon Applications

  • Electrodes: Iridium foil, strip, and ribbon are commonly used to manufacture electrodes for electrochemical applications due to their excellent conductivity and corrosion resistance. These are widely used in fuel cells, electrolysis, and sensors.
  • Catalyst Supports: Iridium is used as a catalyst or catalyst support in chemical reactions, particularly in processes such as hydrogenation, oxidation, and other catalytic processes, due to its stability and resistance to high temperatures and corrosive environments.
  • Aerospace Components: Due to their high thermal stability, iridium foil and ribbon are used in aerospace applications such as spacecraft parts and high-performance thermocouples for temperature measurement in extreme conditions.
  • Medical Devices: Iridium is used in the production of medical devices, especially in radiation therapy applications, due to its radioisotope properties.
  • Precision Instruments: Iridium foil and strip are also used in manufacturing precision instruments where high durability, high-temperature resistance, and corrosion resistance are required, such as in thermometers and pressure sensors.
  • Electrical Contacts and Connectors: Iridium’s excellent electrical properties make it ideal for use in electrical contacts, connectors, and switches that must endure high temperatures and prevent corrosion.

Iridium Foil/Strip/Ribbon Packaging

Iridium Foil/Strip/Ribbon is carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.

Once we have these details, we can provide you with a quote within 24 hours.

We carry a wide variety of iridium products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

DFARS (Defense Federal Acquisition Regulation Supplement) compliance is primarily concerned with the sourcing of materials for defense-related applications in the United States. According to DFARS, certain materials used in defense must be sourced from the United States or qualifying countries.

If you have specific iridium materials that are subject to DFARS, please let us know in advance and we will confirm.

At Heeger Metal, we take this responsibility seriously. We adhere to all applicable laws and regulations, including Section 1502 of the Dodd-Frank Act. Our company operates with a strict code of ethics and is committed to only partnering with suppliers who share our dedication to responsible sourcing. We support the initiatives and programs aimed at promoting “conflict-free” supply chains and work diligently to ensure that our products meet these standards.

Iridium foil/strip/ribbon is used in high-temperature applications, electrical contacts, and aerospace components due to its extreme corrosion resistance.

We offer iridium foil/strip/ribbon in thicknesses ranging from 0.01 mm to 1 mm, depending on application needs.

Iridium foil/strip/ribbon has higher hardness and melting point than platinum or rhodium, but is less ductile.
