Baoji Ruihenghua Titanium Metal Composite New Materials Co., Ltd. is one of the leading manufacturers and suppliers of stainless steel cathode plate and cathode sheet in China. If you're going to buy customized stainless steel cathode plate and cathode sheet made in China, welcome to get more information from our factory. For price consultation, contact us.
Product Introduction
Our 316L stainless steel cathode plate and cathode sheet are permanent electrolytic substrates specifically designed for copper, nickel, and cobalt electrolytic refining and electrowinning. Made with American standard 316L stainless steel, they exhibit excellent resistance to corrosion in dilute sulfuric acid electrolytes. Copper-clad composite conductive beams reduce plate resistance and power consumption. Double-sided seamless laser welding ensures a robust and leak-proof structure. The cold-rolled mirror-polished surface results in dense metal deposition, allowing for complete removal by fully automatic stripping machines without copper or nickel residue. Compared to titanium cathodes, they offer significant cost advantages, stable mechanical rigidity, and a service life of 10-15 years, perfectly compatible with mainstream ISA and KIDD electrolytic production lines. With over ten years of experience in metallurgical cathode production, our products are exported to Southeast Asia, Africa, Europe, and America. We are committed to becoming your long-term, cost-effective supplier.

Core Product Advantages
High-Cost-Effective Permanent Cathode, Significantly Reducing Procurement Costs | 316L Stainless Steel Raw Material Cost is Far Lower Than Grade 2 1. Titanium
As a permanent cathode, it replaces disposable starter sheets, eliminating the labor required for starter sheet production and resulting in lower overall long-term production costs. It is suitable for electrolytic smelters with low chloride ion content and strict budget control.
01
Copper Composite Conductive Beam
Lower Conductive Loss. The integrated copper-clad conductive beam design increases the conductive contact area, reducing the overall resistance of the electrode and the cell voltage. Compared to all-stainless steel lifting beams, it improves the current efficiency of the entire production line and reduces power consumption per ton of metal.
02
Seamless Laser Welding
Resistant to Deformation and Leakage. Double-sided full-welding laser process between the electrode and the lifting beam eliminates micro-gaps, preventing acid penetration and corrosion of the weld. The high tensile strength of the stainless steel substrate ensures that it will not dent or bend during long-term cyclic electrolysis, maintaining stable plate flatness.
03
Mirror-Finish Ultra-Smooth Surface
Suitable for Automated Sheet Removal. High-precision cold rolling and mirror polishing processes eliminate burrs and unevenness on the plate surface, preventing metal crystal adhesion. Copper and nickel metal scales are completely removed without residue, perfectly matching fully automated sheet removal equipment and improving sheet output efficiency.
04
Application Scenarios
This stainless steel cathode plate and cathode sheet are universal permanent cathodes used in hydrometallurgical processes, primarily for electrolytic copper, electrolytic nickel, and electrolytic cobalt production in smelters. They are suitable for copper extraction from low-chloride waste liquid in PCB manufacturing and for small to medium-sized electrowinning production lines. They are compatible with mainstream ISA and KIDD electrolytic cells, achieving a stable precipitated metal purity of over 99.97%.
Product Details
01.
Standard 316L Stainless Steel Raw Material Utilizing original ASTM-certified 316L stainless steel coils, with stable chromium and molybdenum composition, uniform corrosion resistance, and unchanged mechanical properties even after long-term sulfuric acid immersion. For high pitting corrosion resistance, an upgraded version of LDX2101 duplex stainless steel can be selected.
02.
Integrated Cold Rolling + Precision Welding Process The entire plate is cold-rolled, undergoing multiple pickling and mirror polishing processes. The outer layer of the lifting beam is wrapped in pure copper and then seamlessly laser-welded. The edge anti-corrosion insulating strip is integrally extruded.
03.
Comprehensive Factory Testing: Each cathode undergoes flatness testing, conductivity drop testing, acid corrosion simulation, and weld sealing testing, all meeting international permanent cathode industry standards.

Frequently Asked Questions
Q1: What is the difference between stainless steel cathode plates and thin cathode sheets?
A1: Thick cathode plates (2–4mm) are suitable for long-term continuous electrolysis in large factories, offering stronger deformation resistance and longer lifespan; thin cathode sheets (0.8–1.5mm) are lightweight, require lower initial investment, and are suitable for small-batch intermittent production.
Q2: Can stainless steel cathodes directly replace titanium cathodes?
A2: Suitable for electrolyte chloride ion <50mg/L; for PCB high-chlorine etching waste liquid systems, Grade 2 titanium cathodes are recommended for better passivation resistance.
Q3: Can this stainless steel cathode be used with an automatic peeling machine?
A3: Mirror-polished ultra-flat surface, complete and non-stick copper-nickel metal peeling, directly compatible with mainstream fully automatic peeling equipment on the market.
Q4: Can the thickness, length, width, and conductive beam structure be customized?
A4: We support full-size customization. The plate thickness, length, width, copper cladding length, and beam shape can all be adjusted according to the customer's electrolytic cell dimensions.
