Baoji Ruihenghua Titanium Metal Composite New Materials Co., Ltd. is one of the leading manufacturers and suppliers of isa cathode plate in China. If you're going to buy customized isa cathode plate made in China, welcome to get more information from our factory. For price consultation, contact us.
Product Introduction
Our standard ISA process permanent cathode plates follow classic ISA copper electrolysis technology specifications and are the mainstream electrode plates used by copper electrowinning and electrolytic refining smelters worldwide. The main body of the electrode plate is made of US standard UNS S31603 316L stainless steel; the conductive beam is a hollow stainless steel base with thickened electroplated copper cladding, balancing structural rigidity and conductivity. The bottom of the cathode uses a wax-coated separation design, forming two independent copper sheets after peeling, perfectly compatible with mainstream ISA fully automatic peeling machines on the market. Our factory offers two models: the standard model and the upgraded low-resistance ISA BR model. The BR model extends the copper plating to a depth of 55mm, significantly reducing cell voltage and saving electrolysis power consumption. Compared with KIDD solid copper core cathodes, ISA cathodes have lower procurement costs and are easier to maintain, suitable for medium-low acid mist and open electrolytic cell production lines. The plates undergo multiple cold-rolled mirror finishing processes, forming a stable passivation film on the surface, resulting in smooth copper peeling without sticking to the plate, and a service life of 10–13 years. Our factory has over ten years of experience in manufacturing IsaKidd cathodes, and our products are exported to major copper smelters worldwide, including Chile, Australia, and Zambia.

Core Product Advantages
Using a hollow steel tube with an external copper plating structure
Hollow Copper Clad Conductive Beam, High Cost-Effectiveness, High Rigidity ISA. This design results in lower raw material costs compared to KIDD solid copper cores. The hollow structure offers excellent bending resistance, preventing deformation during long-term overhead crane transport, making it suitable for budget-constrained, open-cell electrolytic smelting companies.
01
Separation into two independent copper sheets for easier shipping and processing
A unique bottom wax coating process ensures the copper layers are not connected at the bottom. Each cathode produces two independent single copper sheets, facilitating packaging, transportation, and spot sales. This is the mainstream choice for standard copper refineries.
02
Upgraded ISA BR low-resistance model for long-term energy savings
While ordinary ISA plates only have a 15mm copper plating, ISA BR extends the plating to 55mm, shortening the high-resistance conductive path of the stainless steel. This reduces the voltage drop per cell by approximately 10 millivolts, resulting in significant annual electricity savings for large electrolytic plants.
03
Mirror-finish passivated surface for stable peeling effect
Multiple cold-rolled mirror polishing processes form a uniform passivation film on the stainless steel surface, preventing copper crystals from adhering and allowing for complete peeling of the entire copper sheet without residue. Compatible with all mainstream ISA fully automatic peeling equipment.
04
Application Scenarios
ISA stainless steel permanent cathodes are the mainstream standard equipment for copper electrowinning and electrolytic refining worldwide. They are widely used in open electrolysis workshops with low to medium acid mist and low chloride ion electrolytes, suitable for copper mines in Chile, Australia, and Africa, as well as small and medium-sized refineries. They stably produce 99.99% high-purity cathode copper and perfectly complement a full range of ISA overhead cranes and automatic peeling systems.
Product Details
01.
Genuine 316L stainless steel raw material. Utilizing Baosteel/POSCO UNS S31603 low-carbon molybdenum stainless steel coils, it exhibits stable pitting corrosion resistance under dilute sulfuric acid conditions, and the surface is not prone to warping or deformation during long-term cyclic electrolysis.
02.
Hollow tube composite copper plating process. Hollow stainless steel conductive beams are activated and then plated with a thick, uniform copper layer; the beams and electrodes are fully laser-welded by a robot, and the bottom is precisely wax-coated for separation.
03.
Full-scale factory testing. Each ISA cathode undergoes four tests: flatness, tank voltage, acid mist simulation, and peeling compatibility, fully complying with Glencore's ISA process technology standards.

Frequently Asked Questions
Q1: What are the main differences between ISA cathode plates and KIDD cathodes?
A1: ISA uses a hollow copper-clad conductive beam with bottom wax coating, resulting in lower cost. Stripping involves two independent copper sheets, suitable for open electrolysis cells with low to medium acid mist. KIDD uses a fully enclosed solid copper core without wax coating, offering resistance to high acid mist and lower voltage drop, suitable for closed, highly corrosive gas collection workshops.
Q2: What is the ISA BR low-resistance model?
A2: ISA BR increases the copper plating depth from 17mm to 55mm, reducing plate resistance and saving significant electricity costs in long-term production.
Q3: Can ISA cathode plates be used with fully automatic stripping machines?
A3: The mirror-finish ultra-flat surface and bottom partition structure are fully compatible with all mainstream ISA fully automated stripping production lines worldwide.
Q4: Can the plate thickness and copper plating depth be customized?
A4: Full-size customization is supported. Electrode thickness, conductive beam size, and standard/BR55mm copper plating depth can all be adjusted as needed.
