We supply high-performance, insoluble anodes, including Mixed Metal Oxide (MMO) and Platinized Titanium, designed for precise, uniform, and energy-efficient metal finishing in all industrial electroplating applications.
Request a QuoteElectroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode. The anode's role is to complete the electrical circuit and facilitate the oxidation reaction. Insoluble anodes, such as those made from titanium coated with MMO or Platinum, are preferred in many modern processes because they maintain their shape (dimensional stability), do not contaminate the plating bath, and allow for precise control over the plating chemistry.
| Anode Type | Mechanism | Key Advantage |
|---|---|---|
| Insoluble Anodes (MMO/Pt) | Oxygen or Chlorine evolution reaction. Anode material is not consumed. | Dimensional stability, no bath contamination, precise control of metal concentration. |
| Soluble Anodes (e.g., Copper, Nickel) | Anode metal dissolves to replenish the metal ions in the bath. | Self-replenishing metal source. |
The anodes maintain their original shape and size, ensuring consistent current distribution and uniform plating thickness over time.
Advanced coatings (MMO, Platinum) offer low overpotential, minimizing energy consumption during the plating process.
Since the anode material is not consumed, it prevents the buildup of sludge and impurities, maintaining the high purity of the plating bath.
The robust titanium substrate and durable coatings provide an extended operational life, reducing downtime and replacement costs.
We offer a variety of anode types tailored to specific plating chemistries and desired finishes.
| Anode Type | Coating Material | Typical Plating Application |
|---|---|---|
| Platinized Titanium Anodes (PTA) | Platinum (Pt) | Precious metal plating (Gold, Rhodium), Hard Chrome plating, Electrodialysis. |
| MMO Anodes | Mixed Metal Oxide (Ir/Ru) | Copper foil production, PCB coppering, Steel plate galvanizing, Acidic/Sulfate baths. |
| Titanium Anode Baskets | Uncoated Titanium | Used to hold soluble anode materials (e.g., Nickel, Copper balls) for controlled dissolution. |
