DSA Titanium Anode (Ir-Ta / IrO₂ Coated Mesh)

Name: DSA Titanium Anode (Ir-Ta / IrO₂ Coated Mesh)
Brand: TOPTITECHS
SKU: TT-5179
Availability: InStock

DSA titanium anode with Ir-Ta or IrO₂ coating on mesh. Dimensionally stable, high oxygen evolution efficiency, for electroplating and water treatment.

Products Specifications

DSA (dimensionally stable anode) titanium anodes are coated with iridium-tantalum (Ir-Ta) or iridium oxide (IrO2) for excellent catalytic activity and long service life. Used in oxygen evolution reactions, metal plating, water treatment, and cathodic protection, they outperform traditional anodes with lower overpotential and minimal passivation.

1Product Overview

2Material & Manufacturing

Titanium combines an outstanding strength-to-weight ratio with excellent corrosion resistance in oxidizing, chloride-rich, and acidic environments. The passive oxide film that forms naturally on its surface self-repairs when scratched, which is why titanium components are specified in marine, chemical processing, and electrochemical applications where stainless steel fails prematurely. Grades commonly supplied include commercially pure GR1, GR2, and alloyed GR5 (Ti-6Al-4V), each balancing formability, strength, and weldability for different duty cycles.

At TOPTITECHS, every titanium product is manufactured from certified mill material with full traceability to the original ingot. Dimensional inspection, surface finish control, and mechanical testing follow ASTM standards relevant to the product form, so the delivered component matches the drawing and the datasheet. This material governance is the foundation of consistent performance in demanding service.

7Where This Product Fits

In electrochemical service, electrode performance depends on surface area, conductivity, and catalytic activity. This product is engineered to maximize active surface area while maintaining low electrical resistance and, where coated, a stable catalytic layer (Pt, Ru-Ir, or Ir-Ta) that lowers overpotential and resists passivation at high anodic potential.

Applications span PEM electrolyzers, fuel cells, chlor-alkali, and electroplating, where consistent electrode geometry and coating adhesion directly translate into cell efficiency and lifetime. Dimensional and coating specifications are verified per drawing.

How to select: specify the electrochemical duty (current density, electrolyte, potential window), required lifetime, and whether coating is needed above ~2 A/cm² anodic duty; then define substrate form (mesh, plate, felt) and dimensions. Coating type (Pt, Ir-Ta, Ru-Ir) is selected by process chemistry.

8FAQ

When is coating necessary?

For anodic service above roughly 2 A/cm² or at potentials above 1.8 V, bare titanium passivates and contact resistance rises. A Pt, Ir-Ta, or Ru-Ir coating prevents passivation and stabilizes performance for the design life.

What substrate forms are available?

Mesh, plate, felt, and expanded metal, in dimensions to drawing. Coating thickness is controlled and adhesion is verified by thermal cycling or bend testing.

What is a DSA anode?

A dimensionally stable anode coated with mixed metal oxides for long-life electrochemical service.
