Descriptions
Navkar Metal Syndicate supplies high-quality Phosphorized Copper Anodes that are manufactured from high-purity electrolytic copper cathodes with controlled phosphorus content. These anodes are widely used in electroplating, printed circuit board (PCB) manufacturing, and surface finishing industries, ensuring consistent performance, minimal sludge generation, and superior cathode deposition.
Our anodes are precisely cast and processed to achieve uniform grain structure, excellent dissolution rate, and stable electrical conductivity, making them ideal for acid copper plating baths.
Applications
- Acid copper electroplating (decorative and functional)
- Printed Circuit Board (PCB) and semiconductor manufacturing
- Rotogravure and electroforming processes
- Electro-refining and electro-winning operations
- Base layers for decorative chrome and nickel plating
