The most commonly used materials for stainless steel cathode plates are 316L stainless steel and duplex stainless steel. 316L provides excellent acid and chloride corrosion resistance, suitable for most copper refinery environments. Duplex stainless steel has higher strength and rigidity, reducing deformation under long-term use. The conductive beam is usually designed with copper core or copper-clad structure to lower voltage drop and improve energy efficiency.
We are a leading manufacturer of copper refining stainless steel cathode plates with strict material control and performance certification. Mainstream substrates include 316L (ASTM 316L/EN 1.4404) for general electrorefining and duplex LDX 2101 for high-strength, high-corrosion environments. Conductive beams adopt stainless steel clad copper or copper core structure to lower contact resistance. Edge strips and bottom sealing prevent edge growth and ensure clean stripping. Our products meet ISA/KIDD/ISAKIDD process specifications, with flatness ≤1 mm/m, weld strength ≥ base metal, and service life up to 15 years. They resist pitting and crevice corrosion in acidic electrolytes, ensuring long-term stable operation.
