Product Introduction
Our stainless steel cathodes for copper electrodeposition are permanent electrolytic substrates customized for industrial copper electrodeposition, copper electrolytic refining, and copper extraction from PCB waste. They are available in standard 316L stainless steel and upgraded LDX2101 duplex stainless steel, fully compatible with low-chlorine to high-chlorine sulfuric acid electrolyte environments. The plate surface undergoes precision cold rolling and mirror polishing to form a dense and stable passivation film, ensuring uniform copper ion deposition and a smooth, dense copper layer without crystal adhesion. Combined with copper-clad composite conductive beams and robotic laser seamless welding technology, the electrode plate exhibits low voltage drop, stable conductivity, and high current efficiency. It supports two mainstream structures: ISA hollow copper cladding and KIDD fully sealed solid copper core, perfectly compatible with fully automated stripping equipment. It can completely replace traditional disposable starter plates, significantly saving labor and consumable costs. With a cycle life of 10-15 years, it is a high-performance, cost-effective, reusable permanent cathode for mass production of industrial copper electrodeposition.

Core Product Advantages
Professional copper plating substrate, uniform and dense electrodeposition. High-precision mirror-finish cold rolling process eliminates burrs and unevenness on the plate surface, ensuring a stable passivation film during electrolysis and uniform copper ion deposition rate. This eliminates problems such as uneven copper layer thickness, surface pitting, and roughness, resulting in a smooth and clean copper layer that fully meets the requirements of high-standard copper electrodeposition and refining production.
01
Dual material coverage, adaptable to all copper deposition conditions. 316L stainless steel is suitable for conventional low-chloride copper electrodeposition lines, offering high cost-effectiveness; LDX2101 duplex steel offers double the strength and extremely strong resistance to chloride ion corrosion, specifically designed for complex high-chloride electrolyte environments such as PCB copper extraction. Both materials cover all industrial copper deposition scenarios.
02
Low-resistance copper core for long-term energy savings. The integrated copper core composite conductive structure increases the conductive contact area, reduces the overall electrode resistance and cell voltage, stabilizes current transmission, improves current efficiency, and effectively reduces energy consumption per ton of electrolytic copper, saving smelters electricity costs in the long run.
03
Universal for ISA/KIDD production lines, compatible with automated equipment. Supports two major global cathode structures: ISA (Insulated Electrode) with bottom wax coating and double-sheet copper extraction, and KIDD (Kidney Filter) with fully sealed acid mist resistance. It is directly compatible with all fully automatic stripping machines and electrolytic cells on the market, requiring no production line modifications and offering excellent replacement compatibility.
04
Application Scenarios
This stainless steel cathode is a permanent electrode specifically designed for industrial copper electrodeposition. It is widely used in hydrometallurgical processes such as pure copper electrodeposition, copper electrolytic refining, copper extraction from waste circuit boards, and copper extraction from PCB acid and alkali wastewater. It is suitable for large, medium, and small continuous electrolysis production lines, stably producing high-purity cathode copper and significantly reducing overall factory operation and maintenance costs.
Product Details
01.
Original factory base material, stable performance. Utilizing original 316L and standard LDX2101 duplex steel coils from Baosteel and POSCO, the alloy composition is stable, corrosion resistance is uniform, and the plate surface is not easily deformed or peeled during long-term electrolytic cycles, making it suitable for long-term continuous copper deposition production.
02.
Mirror finish + laser sealing welding. The entire plate is cold-rolled and undergoes multiple acid pickling and mirror polishing processes to ensure an extremely flat copper electrodeposition substrate. The electrode plate and the robotic lifting beam are seamlessly welded together, preventing acid penetration and ensuring long-term stable conductivity.
03.
Comprehensive Performance Testing Before Shipment. Each cathode undergoes flatness testing, conductivity drop testing, electrolyte corrosion simulation, and peeling performance testing to ensure complete compliance with industrial copper electrodeposition mass production standards.

Frequently Asked Questions
Q1: Why use a stainless steel permanent cathode for copper electrodeposition?
A1: A stable passivation film can form on the surface of the stainless steel cathode, resulting in uniform copper deposition, complete stripping without residue, and a reusable lifespan of 10-15 years. It replaces disposable starter sheets, significantly reducing labor and consumable costs for long-term mass production.
Q2: Which material is better for copper extraction from PCB waste liquid?
A2: For PCB waste liquid with medium to high chloride ions, LDX2101 duplex stainless steel is preferred due to its stronger resistance to pitting corrosion and stress cracking; for ordinary low-chloride copper electrodeposition, 316L offers better cost performance.
Q3: Is it compatible with fully automatic stripping equipment?
A3: Yes, it's compatible. The mirror-finish ultra-flat surface has no copper layer adhesion, perfectly matching all mainstream ISA and KIDD fully automated stripping production lines.
Q4: Do you support size and structure customization?
A4: We support full-dimensional customization. Board thickness, length, width, and ISA/KIDD conductive lifting beam structure can all be customized according to the customer's electrolytic cell parameters.
