Iridium-platinum 70/30 electrode wire is built for scale. In large hydrogen energy plants, materials are pushed to their limits every hour — high current density, strong acidity, elevated temperature, and nonstop operation. At DLX, we manufacture Ir-Pt 70/30 electrode wire specifically for these industrial realities, where material stability is directly tied to hydrogen output, system efficiency, and maintenance cost.
Product Introduction
DLX Ir-Pt 70/30 electrode wire is a high-purity noble metal alloy containing approximately 70% iridium and 30% platinum. This composition is widely used in demanding electrochemical environments because it offers an excellent balance between corrosion resistance and electrical conductivity. The higher iridium content enhances anodic stability and resistance to oxidative attack, while platinum supports conductivity and catalytic compatibility.
In large-scale hydrogen energy plants, electrode materials are expected to function reliably for long cycles without performance drop. Our Ir-Pt 70/30 wire is designed as a durable conductive and structural component that can also support catalytic behavior depending on the electrode configuration.
Material Characteristics
DLX Ir-Pt 70/30 electrode wire is engineered based on industrial electrolysis conditions rather than laboratory-only metrics. Key characteristics include:
– Exceptional corrosion resistance in acidic and oxidative environments
– Strong resistance to anodic dissolution
– Stable electrical conductivity under high current density
– Excellent high-temperature oxidation resistance
– High mechanical strength and structural stability
– Long-term performance consistency
These features make the alloy particularly suitable for large installations where downtime is expensive and material failure has system-wide impact.

Industry Trends
Hydrogen energy is transitioning from pilot projects to core industrial infrastructure. This shift creates several material-related trends.
Larger system scale
Electrolyzers are getting bigger, increasing the impact of material reliability on overall plant performance.
Higher performance targets
Plants are designed for higher output and efficiency, placing more stress on electrode materials.
Longer maintenance intervals
Operators want to reduce shutdown frequency, making long-life materials essential.
Stricter material consistency requirements
In large systems, variation in material quality can lead to uneven performance and local failures.
DLX develops and supplies Ir-Pt 70/30 wire with these industrial trends in mind.
DLX vs. General Market Supply
In the general market, Ir-Pt alloy wire may be supplied with limited control over purity, composition stability, or dimensional accuracy. Such variations can translate into uneven corrosion behavior and inconsistent performance in large hydrogen energy plants.
DLX treats Ir-Pt 70/30 electrode wire as an engineering-grade material.
High-purity processing
We carefully control raw materials and melting processes to reduce impurity elements that could weaken corrosion resistance.
Stable alloy composition
Precise control of the 70/30 iridium-to-platinum ratio ensures repeatable electrochemical behavior.
