Iridium–Platinum 90/10 alloy wire is one of the most critical materials used in hydrogen production systems, especially in electrochemical and electrolyzer anode applications. This alloy combines the exceptional corrosion resistance of iridium with the stability and conductivity of platinum, making it suitable for long-term operation in extremely aggressive environments.
At DLX Alloy, we manufacture high-durability Ir-Pt 90/10 alloy wire specifically designed for hydrogen production anodes, where materials must withstand high current density, acidic electrolytes, and continuous oxygen evolution without degradation.
Our Ir-Pt alloy wire is produced with strict composition control, high purity raw materials, and precision wire drawing processes to ensure stable performance and extended service life.
Material Characteristics of Ir-Pt 90/10 Alloy Wire
Ir-Pt 90/10 refers to an alloy composed of approximately 90% iridium and 10% platinum (by weight). This ratio is widely recognized as an optimal balance between durability, catalytic stability, and manufacturability.
Key material characteristics include:
Outstanding corrosion resistance in acidic and oxidative environments
Excellent electrical conductivity under high current loads
High melting point and thermal stability
Extremely low material loss during long-term electrolysis
Strong mechanical integrity in fine wire diameters
Compared with pure platinum or pure iridium, the 90/10 alloy structure significantly improves durability while controlling material cost and processing stability.
Typical Applications
DLX Ir-Pt 90/10 alloy wire is primarily used in hydrogen-related electrochemical systems, including:
PEM (Proton Exchange Membrane) water electrolyzers
Anode frameworks for oxygen evolution reactions (OER)
Hydrogen generation electrodes
Electrochemical research and pilot-scale hydrogen systems
Advanced energy and clean fuel development equipment
The alloy is especially suitable for anode-side applications, where oxidative stress and corrosion are most severe.
