Product Introduction
In electroplating applications, anodes are generally divided into two categories: soluble anodes and insoluble anodes.
Traditional graphite anodes gradually dissolve during operation, causing unstable anode-cathode distance, contamination of the plating solution, and inconsistent plating quality.
Titanium electrodes for electroplating are insoluble anodes with excellent corrosion resistance, stable conductivity, and long service life. As inert anodes, they maintain a constant electrode distance during operation, ensuring:
Stable voltage
Uniform current distribution
Improved coating quality
Reduced power consumption
Lower maintenance cost
Titanium anodes are widely used in electroplating, electrowinning, wastewater treatment, cathodic protection, and electrosynthesis industries.
