Platinum Iridium Alloy  Powder

Applications

High-Precision Measurement and Standards:

Platinum-iridium alloys are used in the production of precision standards such as the kilogram prototype (a platinum-iridium cylinder), which served as the international definition of the kilogram for over a century. The alloy’s stability, density, and corrosion resistance make it ideal for applications where precise measurements and long-term durability are required.

Catalysis:

The catalytic properties of platinum make it highly effective in chemical reactions such as hydrogenation, oxidation, and fuel cell reactions. Platinum-iridium alloys are often used as catalysts in industrial processes that require high thermal stability and corrosion resistance, such as in petrochemical and refining industries.

The high catalytic efficiency of the platinum-iridium alloy makes it valuable in applications like automotive catalytic converters, where the alloy helps convert harmful emissions into less harmful substances.

Aerospace:

Platinum-iridium alloys are used in aerospace for components that need to withstand high temperatures, extreme pressures, and high-stress environments. Applications include aircraft components, rocket engine parts, and satellite parts, where the alloy’s strength, thermal stability, and corrosion resistance are critical for reliability and performance.

The alloy is used in jet engines, missile components, and aerospace electronics due to its ability to withstand the harsh conditions found in these applications.

Medical Applications:

The biocompatibility of platinum-iridium alloys makes them ideal for medical devices. They are used in implants, surgical instruments, and electrodes due to their non-reactivity with the human body.

The alloy is also used in pacemakers and neurostimulators as it is non-toxic and can function for extended periods without degrading. Medical electrodes that are used for diagnostic equipment (e.g., ECG or EEG) often utilize platinum-iridium alloys for their conductivity and long-term stability.

Electrodes and Electrical Contacts:

Platinum-iridium alloys are commonly used in electrodes and electrical contacts, where their resistance to corrosion, good conductivity, and durability make them perfect for long-term use in electronic devices, batteries, and fuel cells.
