Product Introduction
Our 316L stainless steel permanent cathode plate (UNS S31603) is a long-cycle, reusable permanent electrolytic substrate suitable for copper, nickel, cobalt, and zinc electrowinning and electrorefining. Made of ASTM 316L low-carbon molybdenum stainless steel, it exhibits stable corrosion resistance in low-chloride sulfuric acid electrolytes. It features an integrated T2 copper-clad conductive beam, robotically welded on both sides with full laser welding for seamless welds, preventing leakage and weld corrosion. The plate undergoes precision cold rolling and mirror polishing, forming a uniform passivation film on the surface. The metal sheet can be completely peeled off without sticking, perfectly matching fully automated stripping equipment. Compared to disposable starting plates, it significantly reduces labor costs; compared to Grade 2 titanium cathodes, it offers a significant raw material price advantage and a service life of 10-15 years. Our factory has been deeply involved in the production of metallurgical cathodes for over ten years, and our products are exported to Africa, Southeast Asia, Europe, and the United States. We are committed to becoming your stable supplier of high-performance, cost-effective permanent cathodes.

Core Product Advantages
Recyclable permanent cathode, significantly reducing overall production costs. 316L 1. Stainless steel permanent cathodes replace disposable starter plates, eliminating the need for labor and equipment investment in starter plate manufacturing; raw material costs are significantly lower than Grade 2 titanium cathodes, making them suitable for small and medium-sized smelters with limited budgets and low chloride ion content in the electrolyte.
01
Copper composite conductive beams reduce electrolysis power consumption. The beams have a thickened T2 copper core encased in stainless steel, maximizing the conductive contact area, reducing overall electrode resistance and cell voltage, improving the current efficiency of the entire production line, and reducing power consumption per ton of electrolytic metal.
02
Robotic full welding process prevents leakage and deformation. Double-sided fully automated laser flux-free full welding eliminates micro-gaps, preventing acid seepage; the 316L substrate has high tensile strength, resisting bending and denting during long-term cyclic electrolysis, and maintaining stable plate flatness year-round.
03
Mirror-finish passivated surface, compatible with fully automated stripping equipment. Multiple cold rolling and mirror polishing processes create a uniform and stable passivation film on the surface, preventing metal crystal adhesion; precipitated copper, nickel, cobalt, and zinc metal scales are completely removed, compatible with mainstream ISA/KIDD fully automated stripping production lines.
04
Application Scenarios
This 316L stainless steel permanent cathode plate is a standard permanent substrate for hydrometallurgical electrolysis, widely used in electrolytic copper and nickel refining, cobalt-zinc electrolytic material extraction, and copper extraction from low-chlorine PCB waste liquid. It is suitable for continuous large-scale production in large and medium-sized smelters, with a stable precipitated metal purity of over 99.97%.

Frequently Asked Questions
Q1: What is the difference between 316L stainless steel permanent cathode and titanium cathode?
A1: 316L stainless steel cathode has a lower procurement cost and is suitable for electrolyte chloride ion levels below 50mg/L; Grade 2 titanium cathode has stronger passivation resistance, is suitable for high-chlorine etching waste liquid, and has a longer service life, but the raw material cost is higher.
Q2: Can the sheet thickness, size, and conductive lifting beam structure be customized?
A2: We support full customization. Length, width, thickness, copper ladle length, and lifting beam shape can be adjusted as needed to match the customer's electrolytic cell size.
Q3: Can this permanent cathode be used with a fully automatic stripping machine?
A3: The mirror-passivated ultra-flat surface ensures complete and non-stick metal peeling, directly compatible with all mainstream fully automatic stripping equipment on the market.
Q4: Do you provide samples for testing?
A4: We can provide small-size samples for customers to conduct on-site copper, nickel, cobalt, and zinc electrolytic peeling tests. After verifying the production effect, bulk orders can be placed.
