Product Introduction
Conductive beams for electrolysis are the core current-carrying components of electrolytic cells, undertaking the dual functions of supporting the electrode plates and conducting large currents. Our products are manufactured using explosive welding and precision rolling processes, achieving a complete metallurgical bond between the corrosion-resistant coating and the copper conductive core, completely solving the industry pain points of high contact resistance and easy delamination in mechanically assembled beams. Unlike pure copper beams or pure titanium beams, the composite structure combines the excellent conductivity of copper with the corrosion resistance of titanium/stainless steel/nickel: compared to pure copper beams, it has higher structural strength, lighter weight, and several times better resistance to electrolyte corrosion; compared to pure titanium beams, conductive losses are significantly reduced, resulting in energy savings of over 30%. Our products are widely used in the anode and cathode conductive systems of hydrometallurgical, chlor-alkali, and electroplating production lines, effectively reducing electrolysis power consumption and extending equipment lifespan, making them a core supporting component for energy saving and efficiency improvement in the electrolysis industry.

Product Features and Applications
Product Advantages
Metallurgical bonding results in low resistance and high conductivity, leading to significant energy savings: Explosive composite bonding achieves atomic-level metallurgical bonding with gapless and oxide-free interfaces, negligible contact resistance, and conductivity continuity far exceeding that of mechanically assembled or electroplated conductive beams; low heat loss under high current conditions, saving more than 30% of electricity compared to pure titanium conductive beams, resulting in considerable long-term electricity cost savings and a short investment payback period.
Multi-material system adaptability, covering all working conditions: Four material series are precisely matched to different electrolyte environments: titanium for strong acid, stainless steel for general use, and nickel for strong alkali, avoiding rapid corrosion failure caused by incorrect selection of a single material, and customizing the coating thickness as needed to balance service life and procurement cost.
High bending resistance structural design, no deformation over large spans: The rectangular flat cross section optimizes the bending modulus, and the composite structure strength is much higher than that of pure copper beams, resulting in minimal deflection under full load electrode plate suspension; For large-span electrolytic cells, a steel core can be built-in for reinforcement or a thicker corrosion-resistant layer can be added to further enhance structural strength and prevent electrode plate tilting and poor contact caused by bending deformation during long-term use.
Fine end processing for easy installation and connection: Conductive contact surfaces, electrode slots, connecting bolt holes, transition joints and other structures can be processed as needed. The conductive contact surfaces are precisely polished to reduce the contact resistance with the busbar. It can directly replace the original conductive beam without modifying the electrolytic cell structure and is ready to use after installation.
Zero-pollution electrolyte, ensuring product purity: The outer layer of corrosion-resistant metal completely encapsulates the copper core, and no copper ions are released from the electrolyte contact area, which will not contaminate the electrolyte or affect the purity of the electrolyzed product. It is especially suitable for processes with high cleanliness requirements, such as high-purity metal electrolysis and precious metal extraction.
Application Areas
Hydrometallurgy: Cathode and anode conductive beams for electrolytic copper/zinc/nickel/cobalt/manganese, adapted for permanent cathode electrolysis systems.
Chlor-alkali chemical industry: conductive beams for ion-exchange membrane electrolyzers and conductive components for caustic soda evaporation devices, suitable for strongly alkaline electrolytes.
Precious metal extraction: The conductive system for wet electrolytic extraction of gold, silver, and platinum group metals ensures product purity by preventing impurity precipitation.

Environmental engineering: Conductive components of equipment for electrocatalytic oxidation and electrolytic flocculation treatment of high-concentration organic wastewater.

Professional Consultation Q&A
Q1: Under different electrolyte conditions, should the conductive crossbeam be titanium-clad copper, nickel-clad copper, or stainless steel-clad copper?
A1: The core selection criteria are the acid/alkalinity and corrosion intensity of the electrolyte: For acidic systems (sulfuric acid, hydrochloric acid, chloride-containing electrolytes) and copper/nickel/cobalt electrowinning processes, titanium-clad copper is the best choice due to its superior resistance to strong acids and the absence of copper ion deposition; for concentrated alkaline systems (chlor-alkali electrolysis, caustic soda processes) and high-temperature conditions, nickel-clad copper is the best choice due to its optimal resistance to concentrated alkalis and high-temperature oxidation; for general weak acid/alkaline conditions, conventional copper electrolytic refining, and limited budgets, 304/316L stainless steel-clad copper offers the best cost-performance ratio, with 316L being suitable for weakly corrosive environments containing chloride ions. Please provide your electrolyte composition, operating temperature, and current density, and we will provide a precise material and thickness ratio solution.
Q2: How to connect the conductive beam to the busbar and electrode plate to effectively reduce contact resistance and heat generation?
A2: The key is to ensure the flatness and cleanliness of the contact surfaces and sufficient clamping force: First, the contact surfaces are treated with precision milling and polishing, achieving a surface roughness Ra≤1.6μm, free of oxide layers and depressions; second, the connection method is optimized, with bolts evenly distributed and preload controlled when using bolted connections. Conductive grease can also be applied to the contact surfaces to further reduce contact resistance; third, electrode plate connections use welding or dedicated conductive slots to avoid point contact and poor connections. Special attention should be paid to preventing large-area direct contact between different metals to avoid galvanic corrosion; if necessary, transition gaskets of the same material should be added. We can manufacture dedicated conductive transition joints and connection structures for direct on-site assembly.
Q3: What are the common causes and solutions for decreased conductivity and localized overheating of electrolytic conductive beams after long-term use?
A3: Common causes fall into three categories, each with a different solution: First, oxidation and scale buildup on the contact surface lead to increased contact resistance. This is the most common cause; simply disconnect the power, polish the contact surface, clean the scale, and re-tighten evenly. Second, damaged end seals allow electrolyte to seep in and corrode the copper core, resulting in a reduced local cross-section, increased resistance, and overheating. In this case, the corroded area needs to be ground off, and the seal repaired with a suitable corrosion-resistant material. Third, localized delamination at the interface is a common cause, usually due to product quality issues or strong external impact. Minor delamination can be tolerated with downgraded use, while severe delamination requires replacement. Regularly inspecting the contact surfaces and end seals during routine maintenance and promptly cleaning scale can significantly extend service life.
