Product Overview
High-purity graphite anode plates are widely used in electroplating, electrowinning, and electrolytic processes as inert anodes. With excellent electrical conductivity, corrosion resistance to acidic electrolytes, and cost effectiveness compared to platinized titanium or noble metal anodes, graphite anodes provide reliable performance for a wide range of electrochemical applications.

FAQ
Q: What current density is recommended for graphite anodes?
A: Typical operating current density is 100-300 A/m² for standard grade graphite. Higher current densities will increase anode consumption rate. For longer anode life, we recommend operating at the lower end of the recommended range and ensuring good electrolyte circulation.
Q: How long do graphite anodes last in electroplating?
A: Anode life depends on current density, electrolyte chemistry, and operating conditions. Typically, graphite anodes last 6-12 months in electroplating operations. As the anode erodes, it can be machined down and reused until it reaches minimum thickness.
Q: Can you drill mounting holes and machine custom shapes?
A: Yes, we can machine graphite anode plates with mounting holes, tabs, and custom geometries. Please provide your drawings or specifications, and we will produce anode plates ready for installation in your plating tanks.
