Auxiliary Anodes Manufacturer
We redefine industry standards with our cutting-edge design and proprietary coating formulations tailored exclusively for the Metal Finishing sector. TITAN is the auxiliary anodes manufacturer that plating shops and process engineers count on for consistent, contamination-free results.
Auxiliary Anodes Manufacturer for Metal Finishing & Electroplating
TITAN’s understanding of anode precision machining and manufacturing, electrochemistry and the processes requiring precious metal coatings, have served to bring TITAN to the industry forefront. We are one of the leading manufacturers of auxiliary anodes and cathodes for many different applications: from Automotive, to Circuit Boards, to Wastewater.
What Are Auxiliary Anodes and Why Does Your Plating Process Depend on Them?
Auxiliary anodes are supplementary electrodes positioned within a plating bath to redirect current toward low-density zones and complex part geometries that a primary anode cannot plate uniformly on its own. Titanium auxiliary anodes are insoluble, meaning they deliver consistent current without dissolving into the solution and contaminating the bath chemistry.
TITAN manufactures mixed metal oxide (MMO) coated titanium anodes and platinum-plated anodes engineered for critical processes, including electroplating, anodizing, cathodic protection, and wastewater treatment.
Mixed Metal Oxide Coated Titanium Anodes for metal plating
TITAN manufactures a various array of mixed metal oxide coated titanium anodes for plating applications.

Mixed Metal Oxide (MMO) Coated Titanium Anodes for Metal Plating Applications
TITAN’s MMO coated titanium anodes are manufactured on dimensionally stable titanium substrates with proprietary catalyst coatings that sustain consistent electrochemical output across the full service life of the anode. Unlike conventional lead or graphite anodes, these insoluble titanium anodes do not shed material into the bath, protecting solution chemistry and downstream deposit quality.
Common applications include:
- Base metal plating: copper, nickel, and chrome deposition
- Precious metal plating: gold, rhodium, palladium, and platinum
- Printed circuit board (PCB) manufacturing
- Wastewater treatment and effluent processing
- Cathodic protection systems
- Electrowinning and metal recovery
Platinum and Mixed Metal Oxide Coated Titanium Anodes for Cathodic Protection
The use of platinum and mixed metal oxide coated titanium anodes in precious metal plating applications offer exceptional electrical field characteristics and eliminate plating bath contamination as a result of anode disintegration. The increased plating speeds and homogeneous distribution of the electrodeposited layer makes these anodes very inexpensive when compared with conventional type anodes. The application of these anodes is applicable to precious metal plating (Gold, Rhodium, Platinum and Palladium) as well as base metal plating (Copper, Nickel, Hard Chrome and Decorative Chrome).
Platinum-Clad Niobium or Titanium Auxiliary Anodes for Specialty Plating
The use of platinum-clad and plated titanium auxiliary anodes in hard chrome plating applications improve the anode dimensional, chemical and electrochemical stability over various operating conditions which improves the overall chrome deposit quality and consistency. These auxiliary anodes are cost-effective and cause no bath contamination by the anodes.

FREQUENTLY ASKED QUESTIONS About Auxiliary Anodes
What is the difference between MMO and platinum clad auxiliary anodes?
Mixed metal oxide coated titanium anodes use a ruthenium or iridium oxide catalyst and cover a broad range of electroplating, electrowinning, and wastewater applications. Platinum-clad anodes apply 99.95% pure platinum to a titanium or niobium substrate, making them the specification for precious metal plating and environments that demand maximum electrochemical stability.
How long do auxiliary anodes last?
Service life depends on coating type, current density, and bath chemistry. Because titanium auxiliary anodes use a dimensionally stable substrate, they significantly outlast conventional lead or graphite alternatives and can be recoated multiple times to extend operational life.
Can you recoat auxiliary anodes?
Yes! The titanium substrate accepts recoating once the original catalyst reaches end of life. TITAN, through Optimum Anode Technologies, offers recoating services that restore full performance without the cost of complete anode replacement.
How do I choose the right auxiliary anode for my application?
The right specification depends on your process chemistry, current density, part geometry, and deposit requirements. TITAN’s engineering team works directly with process engineers and plating shop managers to recommend the correct anode type, coating, and configuration for your operation.
